It's now possible to install OF updates on a rockboxed Shanling Q1.
Previously these didn't work because the RB bootloader interrupted
the update process.
Updates will proceed as they normally do on a non-Rockboxed Q1,
except at the end of the update you'll reboot to Rockbox instead
of the OF. This is only a minor inconvienience and doesn't affect
the update process.

Now that everything has been refactored into separate files the
main routine is the only thing left to move. Put it in main.c.
