Decided to code some more before sleeping, so there's now another test binary.

The ALS fix from an earlier test binary was slightly broken but not anymore.

Escape button can be used to close the fullscreen clock or flashlight when the device is locked. Battery and temperature values above device lock keypad are now updated immediately. Secure button locks or locks&blanks the screen, depending on autolock value. Pressing the power button while device is locked now locks or locks&blanks the screen, depending on autolock value.

New n800_lock_mode setting is enabled by default on n800 but not n810 and causes the power button to always open ASUI and never close it. Disable it if you want to use the power button to close ASUI.

The dpad center button now does whatever the onscreen lock button does, and it supports long or short presses. When combined with the n800_lock_mode you can always use power+dpad to lock the device.
