Change reprotool project to save whole model into one file

[GoogleCodeExporter]

Change reprotool project to save whole model into one file. 

Current implementation has hardcoded dependency on "project.swproj" file which 
contains actors and references to the use cases. New implementation will store 
whole model in one file which will simplify project traversal, reference 
finding and refactoring. 

Project structure will be shown in outline view.

Note: If it becomes clear that file is too big and it's loading too slow, model 
can be easily tweaked with cross-document contaiment reference change.
