Subject: [PATCH] Make /.rockbox a configurable path

While the bootloader is hard coded to look for .rockbox we do have the ability
to run additional firmware files from the File Browser. However they will most
likely fail unless you have unziped the while new build ontop of the old one.

This patch adds the ability to specify a different root. This is useful for
testing. It also means any messing around or config hacking you do won't
impact your normal working install. You just won't be able to boot directly
into such a firmware.
