Title: Tags are allowed to appear multiple times in suggestions

Since hook_tagging_suggestions doesn't pass which tags have already been added to the suggestion list, one tag can be unintentionally added more than once by some modules.

For exemple, the use of both drupalwiki_tagging_suggest and tagging_vocab_suggest generates duplicate.

Until the module handles more than one vocabulary, I don't think it is quite useful to let tags appear more than once. Or do I miss something ?

Cheers!
