I've added few new functions, fixed existing ones etc. Well tested, you can merge right away.

refreshToken() should be treated as defer - in error function of http.request is treated as $http.

There is a small bug in request function - it's fixed on my fork. ('deffer' might throw undefined errors in some circumstances)

* added function to handle token refresh function, has to be sent as a "data", not "params".

Hey @pgajek2 ! First of all - great job with SOQL Lib. Can you please consider adding support for "HAVING"? Thanks!
