Updated Readme, for new devs.
ALERT TO ALL DEVS!!! delete file include/linux/version.h it's not in GIT
but after changes to Makefile no longer used but somehow loaded and brake
the kernel version detection! BIG problem!

things like this

will fail! and what inside function is ignored!
as LINUX_VERSION_CODE is broken!
when include/linux/version.h is gone all OK again. and code generated for
3.10.0 :)

Also i made some changes for modules compile.

updated exfat! see initramfs for new commit

and exfat-nofuse repo is in my user repos! code inside is the code we
have now in initramfs module.
