When a shader is missing, it'll use a default fallback (prevents loading game with missing DLCs/addons)

Load quickhotkeys prior to loading the game to fix hotkey ordering for "restart the same character".

Removed max level on all fixed artifacts. Material level already restrains them
TEST

Currently the AI makes guesses relative to your real location that increase in randomness every turn they don't see you.  This is very good for simulating intelligent chasing through hallways and such.

Where it breaks down horribly is when the target they're chasing moves a long distance quickly, especially over walls.  If you teleport over a wall the AI's guess cache is still at 1 turn, and if they can teleport too they will highly accurately.

This adds a last_special_movement property to Actors that represents the last turn they did a long distance or LOS cheating movement.  Currently only Actor.teleportRandom sets this.  Any NPC chasing a target that has this value set will have its guess cache set to the maximum randomness.

Any talent/function can set last_special_movement as appropriate.

A more ideal solution would be to have an algorithm with actual exploring/wandering behavior instead of a guess relative to your real location, but this should help.

Fix Actor.timedEffects having undefined behavior when effects are added during iteration and not preserving source

Somehow some talents (Osmosis Shield) can have their temporary values applied many times without being removed.  I can't reproduce it, but checking deactivating_sustain_talent on activation not just deactivation might fix it.

- Can now be targeted through allies (Rot worms, etc)

- Now checks Teleport resistance

- Always moves the target to the closest space adjacent to you

Fid ActorAI.aiSeeTargetPos not checking for invalid target location guesses the first turn it doesn't see the target directly
