* Try to do the right thing when completely reverting a merge (forget that the merge took place)
 * When trying to clone from remote repo to existing local dir, offer to create a subdir instead
 * Tidy up clone-successful notification
 * Add a note to commit and revert confirmation dialogs to tell user if they are committing/reverting only a subset of available files
