Autodetect settings on first start

[niccokunzmann]

When the app starts, it does not guide th user towards a friendly experience:

1. it may use the Sattellite images which are not always available
2. it may need "insecure connections enabled" in the settings

We can check these two:

1. Use Mapnik because this works most of the times
2. Connect to a service via http and https and see if it works.
   • ask the use if they want to auto-connect
   • check the connection
   • change the settings
   • connect again and re-check
   • display a notification about what was changed and if it worked
3. Create a button in the settings to auto-detect the best ones for the phone

To check:

• mapnik
• mundraub
• na ovoce
• fruitmap
• staticmap? #272
