*Created a Theme Downloader with preview, downloading themes from http://wii.spiffy360.com/ (Thanks for hosting them)

NOTE: The images used right now for the theme loader are made out of our old images and if someone can make some new ones go ahead. The themes are downloaded to the path you can set up. The downloaded preview images are cached at "<set up theme downloadpath>/tmp/". The widescreenfix isn't implemented there yet because images will probably be changed.

*Started 3rd SettingsPage

*Added JPEG Loading GuiImageData function and 4x4RGBA converter by r-win from WiiXplorer

*Added ZipFile Class from WiiXplorer

*Added StringToMD5 and MD5ToString to MD5 functions and made it undependable of platform
