Subject: [PATCH] [Issue #32] Add button as submitter outside of submit event

Currently if an fx-action is added to a button within a form, the form is not recognized as the form's submitter and will not be included in the formdata.

This checks if the triggering element is a valid submitter and includes it into the formdata if so.
