Merge pull request #198 from janosvitok/master

Simple Desk locking and LTP reset fixes + fixes for Qt5
NEW: It is now possible to control RGB Matrices intensity

Fixed crash with RGB matrix editor open (again)
Added 2 new RGB scripts: fill columns and fill rows
Fixed "RGB Matrixes" to "RGB Matrices"
Added fixture: Robe_ColorMix_240_AT (thanks to Lorenzo Andreani)
Add Amber color to fixture definitions & click&go

...so the fixtures are created properly; I don't plan any RGBW/RGBA/RGBWA color picker.
