[Imports] Review Facebook road import/assisted mapping

[Stephan Knauss]

Hello,

there had been very little feedback regarding the sample data Facebook 
provided:

https://forum.openstreetmap.org/viewtopic.php?id=57942

I invite others to have a closer look as well.
The sample they had provided was not too bad. Some minor issues, but in 
general acceptable.

Please also check out the recent submits by the various Facebook 
accounts done the last few days.

Important is to point out systematic problems early, so they have the 
chance to adjust their process.

Thanks,

Stephan
