Patch for Bogdan:

UI 
- This patch changes the search context menu in the CEditor, CContentPage and CView: 
    Search > C/C++ Search... 
                File Search > Workspace 
                             WorkingSets 
- C/C++ Search pops up the search dialog with the chosen element filled out. 
- File Search does a text based file search on the Workspace or a chosen WorkingSet 

Core 
- Added some error checking to the dependency generator.
