Tons of methods removed in methods.js,
some new features regarding calls and variable logic

new methods: add and sub, for more safely adding and removing
values from properties
when you add or sub, it calls the "add" or "sub" functions from that
parameter, to avoid having all these psudo accessor functions like "dry"
or "wet" which, while neat for language, were hard to work with
All kinds of logic updates

And so ends day 5 of 7drl. Actually managed to get some good work done
tonight even though I got a bit distracted during the day. Tomorrow:
Rooms! More animal logic! Content content content!
