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

This task does not work on Ruby 1.8.6.
You need to use Ruby 1.8.7 or later.

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)

Adds a new top-level translation string to all locale file (only works for childless keys, probably doesn\'t work on windows, doesn't check for duplicates).

Options:
