sweep2unlock: Add sweep2unlock v0.1

Thanks to Ezekeel's gladoskernel source which helped me
a lot in understanding how to emulate a virtual powerkey press.
The powerkey emulation is largely inspired by his coding for
Touch2Wake (Galaxy Nexus).

sweep2wake: enable dynamic button_backlight

If the screen is offline and you touch the home button (aka start a
sweep2unlock) the capacitive buttons will light up to guide your path.
They will be shutdown again as soon as you lift your finger.
