v1.80 - Added form_action($action) to look up forms by regex containing ...

...$action

1) Bumped version to v1.80.
2) Added form_action($action) to look up forms by a regex containing $action.
3) Modified t/local/log-server so we could test finding 1 form and finding
   many forms using form_action($action). Also bumped version to 0.56.
4) Added form_action($action) tests to t/local/form.t. Also modified the
   test outputs to clearly identify which form_*() is under test (and cleaned
   up some test outputs capitalization).
5) Modified Changes and tags for form_action($action).

I thought v1.80 was appropriate since I was adding to the API.
