Implement default language for node aliases, or better, expose a way to
generate aliases for _All_ languages.

You can read the details of the issue here:
  http://drupal.org/node/321848

NOTE: if the user choose "Language Neutral" behaviour, but a language-specific
pattern is set for a given node type, the latter will be used. This addresses
some comments from other users.

Now I am even more convinced that the UI for this one should be a checkbox and
not a list of language, we want to modify the behaviour of alias creation only
when a language-specific alias is missing.
