Title: Chaining support for Loader - #2165

+ Loader methods return Loader object(Libray, Model, Helper, Language,
Driver and View methods).

Additional:
+ Driver method with an empty first parameter were returning FALSE. Now it
returns Loader object.
+ View loader method returns Loader object ONLY IF third parameter
(which is for returning buffered output) is not TRUE.
