Removed onclick event

Onclick events for submit buttons fire BEFORE submission in Chrome,
keeping this button from actually submitting the form. This is a quick
fix, and a better fix is incoming. (Specifically, the function will
submit the form.)
Make Contact.php submit to itself

Contact.php will now submit to itself instead of an external form
handler.
Yet to be added: contact.php handling the form submission.
Removed .dropbox file

The project isn't even in a dropbox, but it was at one point.
