Fixes + additions

* Renamed 'Manage Admins' to 'Admin Options' and 'Manage VIPs' to 'VIP Management'
* Replaced the DayZ logo with a proper BlissAdmin logo( Notify me if BlissAdmin ever changes name so I can edit the .psd )
* Changed link background colour on the frontpages to green
* Worked a bit on the VIP page, not finished, but half-working( Thought I'd push it eitherway incase anyone else gets around in finishing it before me )
* Made the submit button on all pages look like the black submit button
* Added MarginTop option for the additional logo in the config.php-dist
* Tweaked the footer text
