The Objective-J parser and compiler now handles protocol syntax. The Objective-J runtime has new functions to handle protocols. The method 'conformsToProtocol:' has been added to CPObject as an instance and a class method.
With the new compiler, messages such as `[a in:b]` could not be sent, the "in:" parameter throwing an unexpected token error. This was true both if "in" was the first argument or any of the subsequent parameters (such as in `[a something:X in:Y]`).
