Removed some using statements in mainwindow code behind.
extra check to make sure you're not dropping a folder onto itself
Commented out the image drop on image (to me it seems weird but we can uncomment if someone wants it)
Removed stopwatch since it's no longer needed.
Merge remote-tracking branch 'upstream/master'
Removed method that wasn't needed for drag and drop
Stability fixes for Frame Jumping (wasn't being safe when dealing with polygroups and them not existing on a frame)
Renamed a bool to follow naming Convention (Is instead of just some variable)
Finally found where and how to make it that when you mouse back over the Document after giving focus to the Image Viewer, that it gives the focus back to the document view
(instead of having to click)
Region adding and clean ups
Adding some missing JsonIgnores on Commands (since we still do have an Export to Json option)
Can now copy whole PolyGroups from one frame to the other and either paste ON a polygroup or just the frame (will either overwrite or add)
Started on POC for rotating polygons (not quite correct but getting there)
Added operator overloads to PolyPoint
Merge pull request #25 from TravisEvashkevich/master

small tweaks and clean up.
