v2.3.0: Implemented caching to GET methods

This version implements caching for the different get methods (e.g. getBotlists(String)).
This is used as a sort of ratelimit prevention as the requested data is kept in cache and used for 2 minutes before a new request is made.

Additional changes are:

• getBotlists() and getBotlist(String|Site) now have an additional String parameter used for the cache.
  So the new methods are getBotlists(String) and getBotlist(String, String|Site)
• The JSON used for post requests is no longer a single main field, making this version more thread save.
• You can disable the caching through the RequestHandler (Although it's not recommended).
  • To do this just add the boolean true when making an instance of the RequestHandler.
    Example: RequestHandler handler = new RequestHandler(true);
  • This was suggested by @DavidRockin
