Browse Source 
* - implement framegrabber type option
- framegrabber autoselect
- integrate x11 grabber in hyperiond

* add doxy

* v4l: select device by name
hyperiond: fix x11 grabber connection to kodichecker
config: tune default prios of boblight and v4l

* make v4l name finding case insensitive
