Disable energy savings on increment oled light

Added option to disable energy savings mode when using increment oled light.

Exclusive access mode

• Script refactored to take exclusive control the input device, allowing us to filter out keypresses so that WebOS never sees them. This allows overriding buttons even if they have a default behavior such as the app buttons.
• Added support for other buttons that were previously unusable such as "guide", "search", "voice", and "...".
