Updated to use _get_route instead of constructing the URL's manually.
Updated to use the guild in get and post methods.
Made the domain a dynamic part of the _get_route method instead of a static part of the string.
Refactored simple requests to be more DRY.  Added ability to call endpoints that do not include the domain.
Fixed bug for when the path isn't an array and still needs the domain.
Merge pull request #5 from jackiig/master

DRY'd up code, and added general accessors.
