Merge branch 'vaults-update' into 'master'

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!)
