*Lot's of changes in image processing *Added use of libgd and ImageData class from WiiXplorer. No more crashes with corrupted images and no more restriction to images sizes that are devidable by 4 :). *Added a recource file manager for better access of all files/images for internal files and theme files. Some themes will have to adjust some filenames because we want to use the same filenames for themes and internal source files.
