Add hook_term_path for those who want to give the vocab to FAQ

If someone knows to go into the vocabulary table and set the "module" field to "faq," then many, if not most places where "taxonomy/term/xxx" is created will be turned into "faq/xxx" automatically.

I stuck this at the very end of the module and it works just peachy:

/**
 *  Implementation of hook_term_path().
 */
 function faq_term_path($term) {
  return 'faq/'. $term->tid;
 }

If you like the idea, I will create a proper patch or commit it.
