v3 refactor

Good evening, and welcome to television.
v3 refactor is complete - this is a complete rewrite of just about everything.
If you're still on the pre-v3 version of chr (using sqlite3) - and I really hope nobody is, since that sucked - you're probably boned unless I write a tool to move stuff from the old database format to the new one. Sorry about that.
For those old codgers still using the old version, I made a pre-v3 tag for you to checkout to in case you want stuff. Yup, I'm a great git master.
