removed some garbage from boot_chooser folder
created boot_chooser3.
what's news:
	checking for single malloc() calls.
	checking for init before chrooting.
	should now be able to mount ext4 filesystem images. ( e.g. /data/media/Download/ubuntu.img as device )
*NOTE*
i don't have tested boot_chooser3 because i'm waitin for an emerge.
please test it for me if you can. or wait my next commit.
