*Fixed apply on theme downloader after redownloading a theme
*Removed old theme changing menu (no one ever found it anyway)
NOTE: If a theme now includes a "theme_preview.png" in the image folder, it will be shown in the Theme Menu. If it does not have one than when downloading a theme, the loader will copy the preview from the theme downloader to the theme image folder.
NOTE to Themers: Just fyi, if you badly need to use another format than png for the images whyever, than just do so. Just rename the file from the actual format extension to .png extension. The loader will detect that it is not really a png and use the correct format. Supported image formats by USB Loader GX are png/gif/bmp/jpg/tpl.
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.
