+ Controller Test Case (Request, Response, Layout, Session Support)

! Some changes in configuration constraints
+ Added JSON constraint + assert method in base test case
! Changes in configuration
! Fix issues with mock object creation
! Changes in app/etc/local.phpunit for supporting controller test cases
! Refactored module, almost all the interfaces moved to lib. 
! NOTICE: Constraints are implmented without knowing about Magento system at all, so everyone can use them, just by creating own module that will implement required interface from lib.
