Problem: stuck pinentry causes veil to stuck too

Solution:

 - Write `unfuckup` script which will undo and remove new files in darcs repo.
 - This script is idempotent. If you have clean repo, it won't do anything.
 - This script should be later on ported into the veil codebase itself.

scripts/passveil_unfuckup_dirty_repo
