Fix a bug, and add a couple things. From this commit onward, there won't be a release every time.
- Fix the "restart postLoader" option for USB. It wasn't even attempting to restart the application.
- Add a menu option to reboot the Wii to Priiloader, bypassing its autoboot.
- Let the GC analog triggers change pages when partially held down, instead of only working when entirely pressed.
- Hide the default video mode menu option for Nintendont, it didn't work anyway.
- Hide the manual MIOS install option when under Nintendont and Devolution, they don't use MIOS at all.
