Bug fixes Part 2

- If the internal v4l2 grabber is switched off, it will now be de-initialized (Issue: #542)
- Extended error detection in MJPEG decompress method
- Default instance capture activation if it is missing in the configuration (https://hyperion-project.org/goto/post?id=13656#post-13656)
- Fixed some small (think)mistakes (https://hyperion-project.org/threads/hdmi-grabber.3302/page-2#post-14887)
