Code Optimisations

Code optimisations including the simplification of return statements, replacing
some for iterations with foreach, removal of some unnecessary items such as return
statements for void methods and redundant declarations.
Holo-ify equalizer surface

Use holo_blue as the base color for the equalizer surface
to not clash with the rest of the system colors. Reduce
the size of the control handles so they are not so large
on xlarge displays.
Actionbar & Code Updates

Actionbar updated bringing more style to the UI.

statements for void methods and redundant declarations.
addon.d Script Implementation

This commit implements a addon.d script for compatible kernels that will backup the
v4a driver and updated audio conf files so they survive the flashing of a rom update
where supported.

The script will be automatically installed on supported devices during the installation of
the v4a driver.
