advanced-systemui (0.4.0)

• fix: brightness and volume increment buttons were responding to all touch events
• fix: mute button was changing on down event instead of up event
• fix: clicking the last 3 pixels in process viewer would select offscreen process
• fix: process viewer would stop refreshing if long pressed or a drag ended up back at the beginning
• fix: long press will now highlight/unhighlight as finger is dragged in and out of a button
• fix: changes in service size will now cause widget to refresh
• fix: shutting down while on charger now enters minimal UI mode
• reduced process viewer flicker and made minor cosmetic changes
• improved brightness slider dragging by changing motion delay from 100ms to 500ms
• increased brightness of volume/brightness step buttons when active and dimmed when not active or muted
• changed button down timer from 250ms to 100ms
• volume and brightness step buttons repeat when held down
• swiping across 25% of the button bar changes between primary and secondary widget pages
• split half widgets into their own files and cleaned up UI code so all widgets (full and half) are position independant
• widget positioning can be changed by the user
• new (untested) OpenVPN widget, service is stopped when long pressing flight mode button
• ssh widget now toggles between OpenSSH and Dropbear servers when long pressed
• new lock_and_close setting to hide ASUI when using on-screen lock buttons
• flashlight keeps display from blanking
• long pressing fullscreen clock keeps display from blanking, long press again for normal blanking mode

Changes since last test binary:
* swipe to change widget pages has been fixed
* flashlight keeps display from blanking
* fullscreen clock can be long pressed to toggle screen blanking, icon in corner means screen won't blank
* a timer appears in lock button when attempting to blank the screen after flashlight or clock has prevented screen blanking
* dropbear widget shows number of clients and can't be stopped until all clients disconnect
* shutting down while on charger now returns to minimal UI

I'll try to fix the keyboard locking and tap wakeup problems soon.
