function lexicon_uninstall in Lexicon 6

Same name and namespace in other branches

1. 7 lexicon.install \lexicon_uninstall()

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