function makemeeting_choices_submit in Make Meeting Scheduler 7.2

Submit handler to add more choices or suggestions to a poll form, or to copy the first row of suggestions to the others

This handler is run regardless of whether JS is enabled or not. It makes changes to the form state. If the button was clicked with JS disabled, then the page is reloaded with the complete rebuilt form. If the button was clicked with JS enabled, then ajax_form_callback() calls makemeeting_choice_js() to return just the changed part of the form.
