Feature/small bugfixes (#475)
* Swapped arithmetic and logical bitwise right shift operators * Fixed bug where named class expressions would return ____ * Used tstl.createAnonymousIdentifier instead of manually creating them * Switched around bitwise right shift for 5.3 again and fixed failing test * Fixed issue with class names * Fixed shift bugs * Removed bitshiftright operator * Fixed issues with string concatenation detection * Fixed remaining tests * Fixed strange operator switch
