include GTMNSString+HTML, rename & wrap
change the StacManWrapper api to use Class instead of NSString* to parse

This has two benefits:
 - first, we can just use polymorphism to parse instead of doing a bunch
   of string comparisons every time we parse a single data item, which is
   quite unnecessary
 - secondly, and more importantly, this allows us to easily decouple
   parsing from the client so that we can do some private api parsing
   in our internal project without exposing it to StacMan
