Muximux version 1.0, yeah baby, yeah!

Changed name again - MTPHP was too confusing. Updated readme.

Move application logic to separate file, and add "refresh"-button in …

…the menu.

- Moved all logic to "mtphp.php" (away from index.php)
- Added a button in the top right to refresh (only) the app you're
currently using.
- Fixed overflow issue on Internet Explorer (scrollbars would appear in
the top menu).
