Merge remote-tracking branch 'PA-settings/kitkat' into kitkat-remix
Settings: notification drawer background & transparency

    so after keyguard is mostly done let us start notification drawer
    and QS. First one custom background.....either color or picture
    with custom alpha and ability to set a landscape picture seperatly
     if the user want. (lanscape phone only)

    Compared to the 4.3 included version completly recoded and better
    integrated. No idea what I thought 1 year ago on the old implementation

settings: notification transparency (2/2)

this add back notification transparency...compared to 4.3
it controlls as well the notification icon backgound transparency
which felt in the past dissplaced. As well codecleanup of the old
implementation.

largeIcon support I did not add due that google does not support it
as well at current status...it is only a placeholder in
NotificationData
