New Revision: 75659

Log:
[RAPPS]
- Changed the download process - now ThreadFunc handles the download loop
- Passing values to ThreadFunc as a parameter rather than static members
- Declared .cab download AppInfo static so it won't fade away during the download
- Fixed .cab extraction failing while no rapps folder present
- Visual improvements to the .cab dialog
