Frameworks: notification drawer background (1/2)

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
(landscape 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

and remove the not needed view instead of just hiding it.

fb: notification transparency (1/2)

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
