Preliminary Plain-Tweaks kernel control

Invoke "plaintweak" via adb shell or terminal emulator

Will allow variable settings of the following;
Max cpu frequencies (Highest 5 frequencies)
Min cpu frequencies (Lowest 5 frequencies)
TCP Congestion control
IO Scheduler
Governor

Bugs/Glitches; Governor selection will not function properly
when chosen with a hotplug governor. May cause hardlock/freeze.
