Replace osmdroid with another map library

[rleh]

Replace the inactive and bad documented osmdroid with the currently active developed mapsforge.

Pros/Cons?

[rleh]

Edit: _Mapsforge_

Pros:

• Active developed project
• Vector maps (better quality on high-dpi devices)
• Well documented
• Support for offline maps (but not for online maps? 👎 )
• Vector maps consume less storage space / bandwidth

Any cons?
