Bug fix for unable to execute project after first execution

This does not fix the issue. A fix has been committed to the main IDE repository, commit b9220a6. The issue did not lay in reloading the Project, but in-fact, with VR::Process not properly working when included into VisualRuby. The main reason for it being, that Process is under the module VR, which also has a Thread class defined underneath it, and whenever Process tried to create a thread, it was creating a VR::Thread, instead of a Global Thread class. This commit has fixed the issue.
