This adds a new bootmenu to a magic memorystick of the Pandora battery with some new functions and abilities.

Key features:
* Choose to boot firmware from memory stick, internal flash or the original Pandora mainmenu
* Fix flash1:/ (the one holding the settings and config) by formatting it and creating all directories
* Launch an additional application (PSPFiler or such) with working access to the real flash0:/
* [not yet finished] Launch custom firmware installer (OE / M33) with working flash0:/ access, so it can install the CFW straight from a Pandora boot without the need to downgrade to 1.50 first, no matter of the current state (and version) of the internal flash.
* [not yet finished] Access flash0:/, flash1:/ or memory stick via USB (straight from the menu)
