New test binary.

• asui-settings stub, config button and testing support in asui convenience script
• merged secure keypad battery code with battery widget code
• fix: screen could be rotated from fullscreen clock while in secure mode, not any more
• fix: an ALS theme change would screw up the secure keypad
• battery widget on secure keypad will manually change theme when tapped
• fix: tap throttling wasn't using the correct throttle period
• fix: added a 60 second limit for tap throttling to prevent unresponsive buttons

Let me know if the tap throttling changes cause any problems.

Certain daylight conditions and brightness settings make it extremely difficult to see the keypad when using the black theme. The light level might not be enough to trigger ALS theming and the n800 doesn't support it at all so I decided to make tapping the battery widget change the theme, even if ALS theming is enabled.
