USB Loader GX Release V2.2

New:
- Added game categories and filter games list by categories (Can be imported from WiiTDB).
- Wiinertag support.
- Supporting arguments from meta.xml on boot (--ios=xxx and --usbport=x) (Requires Homebrew Channel 1.0.7+ or 
  UNEO Forwarder v3.0).
- New ehci modules by Rodries with better drive compatibility.
- Added two new video modes to force progressive video mode, 'FORCE PAL480p' and 'FORCE NTSC480p'.
- Added Sneek Video Patch mode.
- Added new 'Inherit' setting for game settings named "Use global". If that option is set then the main loader 
  setting is used.
- Full d2x cIOS support with it's new features (Block IOS Reload, Return To, Sector Sizes > 512).
- Support for sector sizes > 512B with FAT32/NTFS (Requires d2x v6+)
- Real support for simultanious use of both USB ports without switching the 2nd drive temporary off. (Requires 
  Hermes cIOS or Rodries MOD of the Hermes cIOS (recommended))
- Added two new settings menus
- Added saving of game browser position when returning to USB Loader GX

Changes:
- Improved several GUI controls/navigations
- Changed settings menu layout and sorted the items to their correct place (HDD menu, features menu)
- Set games settings to use the global setting by default, set to "use global" to use the main loader settings.
- Use TinyXML instead of MXML (better XML support)
- Updated to new libs (libogc, libfat, libext2fs, libntfs)

Fix:  
- "Return to" option now work for all games, even problematic games like Prince of Persia. (Requires d2x v4+)
- Xflip setting fixed.
- Fix the parental lock of Individual game settings (Thanks to NJ7)
- Fix Theme downloader
- Fixed reset of the loader when loading game with IOS reload and disabled WiiTDB titles
- Fixed timeout timer on startup to count correctly.
- Fixed reversed disc image download when Custom/Original option is selected
- Fixed reload of game list after a game rename
- Fixed horizontal text scrolling
- Fixed booting games by arguments (headless id feature)
- Fixed We Dare game boot (thx oggzee)
