Added option to download txtcode if none is found. The error checking for this is really weak so you might get a "file not found" page saved as a cheat text. But its bettor than nothing.
This should fix the weird freezes and crashes while
installing. The ProgressWindow is now in its own thread
and updates the values fast again.
*Added Speed to InstallProgressWindow
Lets see who got the fastest WiiDiskDrive :P (i got up to 5.8MB/s)
*Changed the Updater source in some ways and added an own thread for it for later AutoUpdate feature (when gamestarting problem after networkinit is fixed)
