Add `the_facetious_terms`, `get_the_facetious_term_list` and `get_current_facetious_query`. FAO @johnbillion
Merge branch 'master' into feature/get_the_facetious_term_list
Swap some arguments in `the_facetious_terms` and `get_the_facetious_term_list`. Correct docblock comments. Return an empty string, not `false`, if no terms. Remove stray `var_dump`. Use `get_query_var`, rather than the `$_SERVER` var.
Sync up the two readme docs.
Check for empty `$term_list` in `the_facetious_terms`, as per [John's suggestion](https://github.com/cftp/facetious/commit/d0ae12bec415e0ddbb781b431daddef437484fd3#commitcomment-3022695).
