function lexicon_uninstall in Lexicon 7

Same name and namespace in other branches

1. 6 lexicon.install \lexicon_uninstall()

Implements hook_uninstall(). There are no tables, so we delete all variables and clear the filter cache. It is left to the user to remove any vocabularies that are no longer needed.
