Project/Session tree

[GoogleCodeExporter]

We need to have projects with sessions.
Each session should have three module groups:
 - Simulation Modules
 - Test Modules
 - Help Modules

each group has a list of modules

Points:
 - We should allow to compare modules from different projects.
 - We should allow to create a copy of module in other project/session
 - We should allow to move (maybe drag & prop) modules between project/sessions
 - Import of module/session/project from other data base should be possible
