From e815601afb0eabe1ef59a2e8d1e0a746c4c33c34 Mon Sep 17 00:00:00 2001

Subject: Implement the ability to embed a bootloader in sansapatcher - the
 --install option installs the embedded bootloader, and running without any
 parameters will cause a prompt to be displayed asking the user if they want
 to install, uninstall or cancel.  sansapatcher now requres a PP5022.mi4 file
 (the Rockbox bootloader) in the current directory when building.
