1.6.6 ai changes

This should make the AI less frustrating.  I'd really like to make the flanking behavior consider distance too, but that change might be hard to do.

Update living weapons and sleeping dragons vaults

Starsapphire messaged me with some updates for them and I added some improvements myself.  
For living weapons: added new "moving" enemy weapon weaker than the animated and poltergeist ones, added support for orcs weapon types, and improved the way the ASCII map generation is handled.  
For sleeping dragons: replaces the sleep effect with a proper dozing effect to prevent use of instant use skills while asleep, bumped up chances of aggroing when picking up loot, added as a possible vault to spawn in Eruan, and bumped classes of the dragons from just wyrmic to wyrmic plus 1 random one for drakes and plus 2 random ones for the wyrm (they're supposed to be deadly even by vault standards after all!)

Less pulling entire floors.

These already ignore LOS, and there isn't any clear reason they should scale to begin with.

Living weapons vault fix

Fix for living weapons vault breaking generation if it tried to generate a whip. Also added a failsafe to prevent future broken generation

See merge request !607

Dynamic zones can now be set to reload lists instead of saving them, using zone.embed_lists
In developer mode all generated maps' entities are now checked for upvalues. Beware evil code! Beware!

Simplified main menu's new game option, with dev mode on it always shows a list of modules, without it only shows if more than one is installed

This is for use in movement effects that bypass actually having to follow via normal walking so they don't home in on players that break LOS too quickly.
