[Dltk-dev] review source module refactoring

["Jae Gangemi" <jgangemi@xxxxxxxxx>]

hello all -

  i'd appriciate it if ppl could take a look at bug 201283 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=201283) and try out the attached patch.

  i'm working on pulling back the remote source code for items not contained within the project, and need to represent that source as an ISourceModule in order for things like parsing, etc to work on it, and the addition of those sub-classes makes it much easier to add new implementations. :)
