redPanther f88cd3a230 extend effect engine with qt image effects (#249)
* - effects now can use qt image effects
- rainbow swirtl is now suitable for any led layout - including matrix

* fix rainbow effect

* effect: add radialGradient

* fix some js errors

* optimize code

* try fix travis test not working as expected

* fix default config files

* fix config
