Nerfed cooldown and healing on Bathe in Light

Staves accuracy bonus is now halved for short staves

Generic trees

- Removed the Dual Weapon Training, Acrobatics and Field Control trees from players. These are still present for backwards compatibility. Escorts no longer grant these trees or talents from them
- Heightened Senses now grants see invis/stealth and damage reduction against unseen. Trap effects have been removed
- Track is now present in Tier 2 Survival
- Charm Mastery has been renamed Device Mastery, and grants the Trap effects of the old Heightened Senses
- Danger Sense has been added to T4 Survival. Grants a large damage reduction effect on falling below a life threshold. Has a cooldown
- Piercing Sight and Evasion have been removed from Survival
- Mobility has been restructured with the following talents (in order): Disengage, Tumble, Trained Reacions, Evasion
- Disengage now also grants a movespeed boost and reload effect, as well as 1 turn of evasion
- Tumble now has a shorter cooldown and no cost, but causes the cost to rapidly increase if used repeatedly
- Trained Reactions costs less and scales off Defense
- Evasion has a stamina cost and scales off Dexterity only
- Parry has been renamed to Dual Weapon Mastery, and also grants offhand damage and slightly increased parry chance
- Duelist's Focus and Feint have had their effects increased
- Marauder now gains Duelist
- Total Thuggery now drains 6 stamina each turn rather than 12-6 stamina each hit
- Lethality grants critical strike damage bonus
- Coup de Grace resets the cooldown on Stealth on kill
- Increased the effect of Soothing Darkness
- Fixed a few typos
- Added Light Armour Training to Combat Training. This grants defense and armor hardiness when wearing light armor, and on moving into a tile adjacent to an enemy will grant a brief boost to % defense and stamina regeneration
- Antimagic Anorithil escort now grants Feedback rather than Field Control

Stairs can not be used for some turns after a kill (0 on Easy, 3 on Normal, 5 on Nightmare, 7 on Insane, 10 on Madness)

Ogres's Writ Large lets them get a 6th inscription slot as before, but they have to use a category point to actually unlock it

Buffed Highers (Gift also gives healing mod%, Overseer grants telepathy on hit, Born into Magic has better numbers)

Dwarf Stoneskin fully ignores the triggering attack, and correctly states it has no cooldown and can re-proc while active

Buffed Ghouls (Ghoul provides more stats, Ghoulish Leap provides a global speed boost on landing, reduced Retch cooldown a little, increased Gnaw stats reduction and ghoul spawned is fully controllable)

Buffed Skeletons (Skeleton gives more str/dex, reduced cooldown of both Bone Armour and Re-assemble)

Bathe in Light does not provide nor strengthen shields anymore, instead it gives a fire and light damage buff if the creature already has a shield

Cornacs start with one more generic point, because all other races have one pre-spent in their racial tree and they don't

ActorStats Fix

ActorStats will automatically clone a stats table provided with an actor definition, to prevent multiple actors referencing the same table.  (Static definitions, like those in ToME necrotic minions)

Entity.init will automatically initialize the compute_vals table for temporary values.
