Fixed problem when running on stretch (#47)

* Fixed problem when running on stretch

These addistions will do this:
- Try running it normally (so if this is fixed upstream, we don't need the rest of the additions in the future)
- If first tryf fails, missing dependencies are downloaded, and tre installer runs 1 more time.

Testet with the current version on Hassbian 1.3

* Added mention that this is an workaround
