Restore Quick Pulldown & Correct Brightness tile.

Commit removes the inclusion of the SwitchToSettings function from the NotificationPanelView to restore the correct Quick Pulldown functionality. SwitchToSettings function remains in the code until I can fully implement this whilst allow full and correct function of the Quick Pulldown.

Modification of the BrightnessTile to correct non-functioning behaviour, prior to this commit the Brightness Tile made no change to the screen brightness. The tile now functions correctly

am: Allow more hidden apps on devices with lots of RAM

 * If more than 1.5GB is present, allow up to 40 hidden apps.
 * Number is somewhat arbitrary, but was found to work well on D2.
 * Also look at the sys.mem.max_hidden_apps value if given.

Please don't hardcode strings!

This avoids translations and clutters up the code really badly.
Uppercase

Just to keep consistency
