Make objects know what inventory they're in.

Inspired by the mess that is Wintertide's special on hit. As of !693, combat tables and their objects is now a two-way association. This MR aims to make the object-actor association similarly two way. Items should know where they are and who is holding them, which is accomplished by setting `o.in_inven`, which holds `o.in_inven.actor` and `o.in_inven.id`. This prevents requiring obnoxious searches of inventories for an item in question, and prevents potential search collisions (as `define_as` is not a perfect identifier).

**This MR is save safe, although any behavior reliant on this will not apply to objects without changing their position in inventories.**

Fixes Moon & Star set bonus.

Fixes the set bonus from Moon and Star. The `special_on_hit.fct` bit of its damage had a misinterpreted argument: the first argument is not `self` but the weapon's `combat` table. Luckily the combat table now has a reference to the source as of MR !693.

**This MR is save safe, but old copies of the items will still have the broken behavior.**

See merge request !801

Fix chest graphics bug

Fixes the bug that occurs when golden chests spawn on tiles that already have `add_mos` additional graphics. Since the golden chest expects the chest graphic to be in a particular spot in the list, the act of replacing graphics with the "open chest" often creates unusual behavior like giant open chests.

**This MR is save safe.**

Refactor melee hit proc

1. add two callbacks: callbackOnMeleeProject used for effects similar to melee-project and should be triggered before weapon's on-kill effects; callbackOnMeleeHitProcs used by the victim to trigger on-hit effects
2. move many melee procs in attackTargetHitProcs into related talents/effects by callback and thus greatly simplify this function
3. remove the obselete attributes "damage_backfire","movespeed_on_hit"
4. remove several unique talent attributes "shattering_impact", "knockback_on_hit", "onslaught"
5. slightly reorders the proc order, which should not make much difference though.

 * BALANCE: Change Blood Rush’s bleed calculation to work the same as Blood Bath and Scoundrel.  Lowered bleed multiplier.

Revise Conveyance

1. slightly reduce the mana cost of Phase Door, it's somewhat too much for a basic mobility talent;
2. remove the 35% failure rate of teleport, increase the mana cost, cooldown and reduce accuracy instead;
3. makes it possible to open vaults while Probability Travel is sustained

btw, makes Body of Stone not break when bumping to attack others.

See merge request !782

Fix Radiance's lite radius should be integer



See merge request !781

Revise Cleansing Flames

1. makes it instant to compensate the loss of passive mode, and the opportunity to remove several debuffs per turn;
2. rewrite the formula of cleanse chance each turn, to use actual talent level instead of raw level and reduce the cleanse chance beyond player's talent level;
3. makes it dealing as much damage as the description says, currently it deals a fixed 10 damage. 

If this is rejected, then the part 3 might need a standalone fix.

Faster!

This merge request consists of several independent commits which aim at making ToME4 faster:
1. Add cache for particles & shaders to avoid loadfile & loadstring in game;
2. Adjust the record of recent logs, making it faster and takes less space under extreme situation; 
3. Add cache for ShowChatLog dialog, making the scrolling smoother;
4. Reduce the frequency of player's 'hit_warning' particle effects, which might spam too much (each damage number may create a particle effect).

See merge request !749

Modify Step Up

## Change
1. Each kill provides a 2-turn buff that gives 1000% movement speed in several moves, and any action other than moving will remove the buff.

## Reasons
1. Removes raw talent level usage & removes old-fashioned callback in Actor.lua
2. Makes Step Up more predictable and reliable, that no matter how much energy you have (which you cannot know in-game), you'll always benefit from Step Up and do not need to guess the remaining steps you could make.
3. Talent level above 5 gives small bonus

(for 1.8) add power vs save description for talents

Currently, power vs save mechanism is not explained in game, and players can only tell which power/save the specific talent is using for debuff/knockback/... by experience or diving into the code.
This merge request add more details in the descriptions of talents, in the form like (Physical Power vs Mental Save).
Some helper functions are also provided in DescHelper.lua.

Besides, some minor bugs have been fixed, most of which are inappropriate power used in complex damage type. 
Higher draconic T1 is worth noting that it contains 5 damage types, each one uses a slightly difference power. This merge request changes that to use physical power & mindpower, whichever is larger.

Note: This merge request changes many files and brings much work for translation. Besides, I currently have no access to dlcs' repo, and the work for dlcs' talents description might need to be done by someone with the access.

Pulls the actual parsing of a hotkey into an icon out into its own function

Modifies `engines\default\engine\HotkeysIconDisplay.lua` to better support addons. The current call to `display()` draws every hotkey over the course of a nested iteration, which means that if someone wishes to modify this behavior (e.g. have flagged talents use a different border color, or support multiple talent icons to denote different states of a talent), the entire `display()` function must be entirely replaced. This isn't ideal as these modifications are mutually exclusive.

This MR splits the actual parsing of a hotkey into a `displayHotkey()` function (with appropriate arguments) so that addon developers can safely superload the hotkey drawing behavior.

**This MR is save-safe.**
