multi fix commit (#112)

* multi fix commit

- refactoring leddevicefactory
- adalight: default for "delayAfterConnect" is 1s now - needed for most arduino's because of there special behaviour on open
- fadecandy: new option for disabling configuration send - if you want to keep your fadecandy defaults
- Hyperion.cpp: simplify createSmoothing discussed in #105
- smoothing:
-- add option for continuous output
-- when updatedelay>0 and continousOutput is disabled, buffer is flushed correctly after no input is detected

* add doxygen to travis
