Modified  login.php and funcs.php to customize

The modified files are originally from the usercake installation,
but needed to be modified so that users are redirected to the page
they were originally trying to access after being logged in.
Removed Captcha and Resent Activation

Removed capthca code from register page, and deleted captcha.php.

Updated left-nav to not display Resent Activation, because just
usging the admin setting was not working.
Stylizing Usercake stuff

I added more custom styling to usercake stuff, but I still have
a lot of pages to go.  Though once I'm happy with the few pages
I have done, applying the updates to all the other pages should
go pretty quickly.
