redPanther 5ea3c752b5 new brightness handling (#430)
* clean color adjustment

* now a prio duration of "0" means infinity

* implement dynamic 'just in time' initialization

* implement new brightness handling

* cahnge access level

* i18n fix

* - cleanup brightness stuff
- update webserver, now with initial ssl support

* - backlightThreshold is now 0-100 instead 0-1
- better performance for brightness - use piecewise linear instead of sqrt
