Removes a translation string from all locale file (only works for top-level childless non-multiline keys, probably doesn\'t work on windows).

Options:
  key=key_1,key_2    Comma-separated list of keys to delete
  skip=en,de         Comma-separated list of locale files to ignore (filename without extension)

Options:
