Small fixes

Thar you go.

Fixing NPC target passing from exploding the game

*shakes my fist at Hachem_Muche* players can have ai_state but don't have aiSeeTargetPos!

Save my effects

Currently, in the early game save duration reduction is almost always zero, regardless of save values. This is because the effect durations are low.
This proposed change makes rounding more beneficial to players, making it random based ont he fractional part, so players see duration reduction at least sometimes.

Npc target passing fixes

Hostile NPC's will not randomly agro other NPC's at long ranges.
NPC's will alert each other to the player more freely (and at greater range based on game Difficulty), so that they don't ignore the player when their allies are killed right next to them.
Player summons will not target Cold Flame Traps when they are damaged.

Remember traps&events

Makes known traps and event generated terrain effects remembered on the map and minimap (with distinct colors for each).

Fixes some bugs that were causing the nice tiler to overwrite modified grids for some events.

Makes overlapping event terrain effects behave nicely.

Adds "Lua inspect [Trap]" to the map menu in debug mode.

Note: May need new particle effects to make remembered area effects out of LOS look better.

Charm power descriptions

Updates the power descriptions of charm powered boots, cloaks, light-armor, mindstars, and staves to be more descriptive.

Minor bugfix to Object:getUseDesc to reference the correct actor

Updated resolvers.charm to allow specifying additional .use_power fields.

Small fixes

Mainly concerning reshape weapon-armour so auto-reshape is not such a costly thing and works more normally via callbacks and not via black magic.

Randart egos fix

Fixes a problem with ego definitions possibly not being loaded during randart generation.

More fixes

balance tweaks etc.
