/******
v.1 - kinda quick and dirty, but it does the job for now

Checks for custom "required" attribute for required elements. If "required" exists, the field is required. Later, I'll add a password and email check.

Alert lists the required fields that were left blank and turns them red (plus their label, if there is one) and focuses on the first unfilled required field.

Submit check makes sure only first click of "submit" button registers, so user doesn't keep clicking submit.
