add limit for write to leddevice (#432)

* add limit for write to leddevice

* add to default config

* add i18n

* extend xmas effect

* fix indention

* add check for minimum brightness

* adapt effects to fading and new minWriteTime

* remove old latchTime
rename minimumWriteTime to latchTime
make it as dev specific option

* set default for rewriteTime to 1s
pause smoothing on color too

* reenable smoothing for color - it looks nicer :-)

* fix timeout timer
