implement set videomode via json api (#457)

* implement set videomode via json api

* refactor grabbers:
- new base class
- move shared code to base class

* fix osx

* rework all cmakelist files with auto file collection. except leddevices (need further restructuring)

* store current video and grabbing mode

* add json stuff

* remove grabbingmode - we do not want to expose it
