potential matching page loading issues

Potential Matching page doesn't load, badly organized

Also fixed the invalid signups process so it doesn't just send an email but also shows the invalid signups on the matching page

Also put in a notice when assignments aren't finished loading

This issue (and pullreq, sorry :( ) have become obsolete:
