All functionality to rules, add tests, remove unnecessary rules

@BenDoyle @dklassen @prburke 
All right think this one is worth merging -- I haven't tested deploy rule (need two up votes). If one of you could put a :+1: on this https://github.com/karlhungus/nomic/pull/14, i'll test deploy rule.

The Good:
 - Rename rules to be more obvious
 - Move all endpoints to rules (not sure if this is good)
 - Make deployment/merge/comment dependant on execution of previous rules, but inside a rule

The Bad:
 - Not a lot of tests
 - Not sure about the usefulness of having all end points in rules
 - Deploy as yet untested
 - Ordering totally hard coded and silly
 - Removed all but absolutely necessary items (`bad_word_rule`, `haml`, `slim` -- sorry but i judged these as unnecessary to the kernel of nomic, am willing to add these back if people feel strongly like they should be included)
