The +heal command now requires permission to be used on someone, which they can grant through +heal/permit <name>. Crafting commands will now give a masked name if the crafter is in the room it's done in (if not done by their shop, in other words).

Converted all of Arx's database models to take advantage of some caching Evennia provides, which should make things much faster in some cases as well as more reliable (less caching bugs, hopefully). This was a major change, though, so let me know if you see anything strange.
