dimok321 0908027ad8 *Fix for ntfs writing
*Cache size reduced which results in a bit slower writing but is more stable
*Fix for the gameinstaller ProgressWindow
*Added NTFS unmount on exit

WARNING:
The USBLoaderGX installer seems to be broken in some places. There are sometimes random freezes or crashes even on fat32. Those arent bad on a fat32 filesystem but can damage the whole partition on ntfs. Using the installer on ntfs is still very risky. You have been warned!
