 Just ran a mapping party, and multiple users were editing the same area,
 resulting in some conflicts of edits.

 Now Potlatch2 stops the save operation, and a modal window alerts the user
 to the fact that there is a version mismatch, and even gives a ID of the
 offending object. There is a Yes option to retry (with exactly the same
 result, as nothing has changed), or a No to cancel upload.

 Unfortunately, a version conflict might as well crash Potlatch because
 there is no way for the user to do anything about the conflict and he is
 stuck with losing all of his work!

 What would be needed is for Potlatch to make the user aware that there is
 a conflict, and leave out the offending features (possibly highlighting
 them), but finishing the rest of the upload.

 This way, the user could save (virtually all of) his work (at the moment,
 his only option is to lose all edits and restart), and reload the data to
 redo and resolve the conflicting edits.
