Frontlight Adjust KUAL+ extension

[j.p.s]

I've made a KUAL+ extension to make custom adjustments frontlight brightness. It would be nice if there could be a LAMP_RAMP (or whatever name) for the frontlight like there is FONT_RAMP for font size, but as far as I know there isn't one. This extension has 4 buttons to linearly brighten or dim by and 20% or 10%, 3 buttons to set fixed custom brightnesses, and one button to turn the light off. All these percentages and fixed values are trivially easy for anyone that can use a text editor, no programming required. Unfortunately, the adjustment is lost whenever the Kindle goes to sleep and must be set again. When the setting has been boosted or dimmed, the numerical brightnes is displayed near the bottom of the KUAL menu, and the same or other boost or dim button can be tapped again. Also, a boost then dim does not quite restore the same value, so even finer adjustments can be made.

A lot of customization can be done by changing the menu.json without having to change the lightadjust.sh script.

I have only tested it on my Voyage, but it should work on other jailbroken frontlit Kindles.

The extension and a screenshot of the menu are attached.

More information later, possibly next weekend.
