#2 cleanup

[phrearch]

This is a (unfinished) cleanup attempt of Redux. In short these things have been modified:
* Replaced all short tags with <?php
* Modified quoting in SQL statements
* Moved and cleaned up most of the html styling to a stylesheet(admin and frontend)
* Modified menu to use css-only
* Added a Joomla-modified theme to Redux
* Added limited Remote-admin support (thanks to Olish)

I will try to move some of the logics to classes, and further clean up the code.
