* Rejig frontlight warmth API to more closely match the existing API, and, hopefully, clarify some of its quirks, and reduce boilerplate and duplicate code in platform implementations. * Tweak Kindle:setDateTime to prefer using the platform's custom script, as in interacts better with the stock UI. And make the fallbacks handle old busybox versions better. * Add Kindle PW5 support ;). * Add warmth support to the Kindle platform. * Random TextBoxWidget cleanups: make sure we immediately free destroyed instances. * FrontLightWidget: Refactor to make it slightly less obnoxious to grok and update; i.e., separate layout from update, and properly separate brightness from warmth handling. Move to simpler widgets instead of reinventing the wheel. * TextBoxWidgets: Implement `setText` to match TextWidget's API, as some callers may be using the two interchangeably (i.e., Button). * NaturalLightWidget: Make sure we pass a string to InputText * InputText: Add debug guards to catch bad callers not passing strings ;).
