New test and settings binaries.

• moved power button and device lock settings to their own pages
• power button double-tap support and actions for secure and normal mode
• lock and blank actions for the power button
• increased power button long press from 1 second to 1.5 seconds, to match MCE

This release changes the names for the power_action and secure_power_action keys so you'll have go change them back from defaults.

Double-tap support is enabled by default which causes a one second delay before the power button reacts to single-taps. If MCE doesn't have a double-tap action and you don't want ASUI to have one then you can disable support.
