No more LOW RAM on screen ON. less multi task but less dead kernels.
CORTEX: Disabled all KERNEL/MEM/FS tuning. for now.
Allowd more aggresive OOM kill.
Added more min free RAM to protect kernel for death.

Now all the tuning will be as KERNEL code tuned.
After tessting with sdcard bench that can be trusted! this is the BEST!

on 1024 = 100MB transfter test 275.48Mb/s
on 2560 = 100MB transfter test 371.75Mb/s

much better!
Pulled CM10.1 kernel init changes. for now only charger bin changed.
CORTEX: performance to wake_boost rename to remove confusion with
performance profile! + small rename in CENTRAL_CPU_FREQ
+ removed "freq_cpu1" ...
Set KERNEL_SCHED on sleep same as on wake, wakeup faster and no side
effects, for now KERNEL_SCHED is DEFAULT. till i will have time to test it more.
