Multiboot Firmware Root Redirect - WIP

Loads external drive into root namespace
Root Redirects can now be put into different folders
For instance placing '/_test' into SD1/rockbox_main.<playername>
will redirect to /<1>/_test/.rockbox
Debug menu>Bootdata now has root directory listed in addition to RAW Bootdata

Redirect root work from Michael Sevakis g#1556, RESTORED -> g#4256
