Remove unnecessary updateSurfaceScreenOn call.

This change stops updateSurfaceScreenOn() from being called one time
right after another. It's called at the end of stayAwake(boolean awake),
which is called right before updateSurfaceScreenOn() in release().
keyguard: enable magnetic target if no custom targets defined

When no custom target is defined (the "reset" button is pressed
in settings), the unlock target will always be at the right
regardless of the direction the user dragged to.

This commit brings the navigation bar long press behaviour to
pie controls.

Two things will be considered for long press:

* Long press on BACK will kill an application if enabled within
  the debug options.

Patch Set #2:
* Jacob's colours

Patch Set #3:
* More blueish colours
* Using a longer time out for long press
  (getLongPressTimeout() * 2)
* Moved killForegroundAppication() around

Patch Set #5:
* Shortened long press time out a bit
* Adjust time for info shade dynamically

Fix Photosphere/Camera FCs

Photosphere is setting a few parameters "blindly"
while the API says it should check the device capabilities first.

On TF101 (and probably other devices) the camera HAL doesn't handle
FLASH_MODE & SCENE_MODE and so it sends the required RuntimeException
for these, which makes Photosphere FC the Camera app.

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

Fix based on following Team EOS patch: https://review.teameos.org/#/c/1598/

Many media files and source code files were marked as executable in Git.
Remove those.

PowerMenu : Improve keyguard filtered actions

Replaces the check for visibility of lockscreen with the state
of the keyguard instead. This avoids the situation where actions
returning false from showDuringKeyguard, are still shown if user enters
emergency call screen.

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.
