fixes  variable names
updates readme and docblocks for response refactor
** BC-BREAKING CHANGE - accessTokenResponseType parameter in server class is redundant.  This can be derived from the responseType parameter already passed in.  Getting rid of it
adds setters for controller classes, standardises order of the controller classes, moves protected methods to bottom
adds 'createDefault' methods for all controllers - more accurate naming of functions
** BC-BREAKING CHANGES ** - changes TokenController constructor so ClientAssertionType is now the third parameter instead of the first, and it no longer accepts Storage_ClientCredentials, but has to be ClientAssertionTypeInterface
allows for injection of tokenType into the server object
