LDCad 1.6 Beta 2a (win+linux)

[Merlijn Wissink]

I think I found a bug, or at least something that's not completely user-friendly.

• I open a model from disk.
  
• I remove all submodels except one from the main file (note: the main file does not have any parts, just submodels, maybe that has something to do with it?)
  
• Then go to cleanup and make it remove all submodels not used by the main file
  
• Then hit save
  

Result: it doesn't save anything to disk. All the operations work fine, it just doesn't save anything. It also doesn't give a warning of unsaved progress on close. I can make it save by adding a brick to the main model, then hit save and then remove the brick again.
