SystemUI: fix memory leaks

ContentObservers are being registered without being unregistered,
causing old objects not to be garbage collected. This causes memory
leak if the classes are destroyed and recreated throughout the
device's uptime.

SearchPanelView is recreated every time the screen is turned on.
StatusBarIconView is created every time a notification is triggered.

Fix Photosphere/Camera FCs

Photosphere is setting a few parameters "blindly"
while the API says it should check the device capabilities first.
On TF101 the camera HAL doesn't handle FLASH_MODE & SCENE_MODE
and so it sends the required RuntimeException for these which makes PS to FC

=> check device capabilities & ignore these 2 parameters if the device doesn't support them.

FW: Fix AwesomeAction constants

Fixes 3 'Blank' entries in NavBar/Custom Toggle actions.
This was due to someone (SteveSpear!! :))  Adding actions
to the AwesomeActions variables without putting appropriate
string & drawable returns.
