Login System!

For some reason the entire backups directory found it's way into this
commit so a bit of shuffling had to be done first to stop it. Not
entirely sure how secure the login system is just atm but it's built
around a session checker and boots you back to the login page if you're
not logged in to try maintain some security.

The other thing i've implemented is an access control mechanism that
removes the "Submit" button from forms if you don't have the correct
access level. This will be handy if you want to implement a few accounts
to keep an eye on things and possibly just keep a few internal things
updated rather than making content, may turn this into a "roles" system.

Fixed a lot of weird and wonderful bugs where things weren't echoing
properly and found a lot of herp derp missing tags and stuff like that
all over the place so the admin panel looks considerably cleaner now...
to me... i think...

SQL Dump included!
