Fix code/file tidy

Fixed incorrect <br/> tags in login.php and removed incorrectly
built LESS files
Fix login IE8 Layout

Login page infobox would wrap underneeth the login form. Adding a float
forces the layout to behave correctly.
Fix moved additional CSS file into LESS

Added Paul's CSS changes into the correct LESS files. Saves having a
different CSS file for changes and changes will always be inculded
when LESS is built.
