released 0.9.2-beta

Mostly for the benefit of the people volunteering to test our navigator,
I released a new beta-version 0.9.2-beta.
It contains a simple configuration-wizard that pops up the first time you start
Traveling Salesman and helps you downloading a map and installing your GPS.

I also made it clear that downloading .osm -files works with api0.5 and with api 0.6 -files.

Note that this version contains a known bug with zooming recently introduced. I'll release a new beta
when this is fixed.

Greeings,
Marcus
