updated android toolchain to ndk-r8e with more, but not complete c++11 features

- thread and mutex library is now available
- std::string::to_string() still missing
- remove small obsoltete include path for android built
- removed obsolete todo since there is no way to implement this more easy in c++11 as we already did!
Merge branch 'scripting' into dev
fix merge bug
fixed android build with adt17
use xml instead of code to instantiate VolumeView
added vertical support to VolumeView
relayout SetBrightnessFragment
added RgbFragment with three VolumeViews to configure red, green and blue part seperatly
- fixed missing new files
- add color support to VolumeView
- fixed bug in ledstripe_setcolordirect blue and red were mixed
- use setcolordirect for android setbrightness and setRGB
- renamed android namspaces to WyLight to fix bug with automatic exception generation
fix warning
fix ledstrip unittest, we had a bug in setcolordirect. we did only a memcopy but setcolordirect has to swap red and blue because the led_array is in reverse order due to spi cntroller interface
