Mapillary v4 API support
* Most API calls should only be called once (this should reduce network
traffic)
* It currently appears that detection tiles are not shown
* There is no current method to get detection geometry to show in the
image viewer
* Image loading has been moved off of the EDT (this should improve
performance of the map view -- time taken to image shown is still the
same)
* Some naive handling for server errors exist (i.e., we don't crash).
* Hitting API limits is not well handled -- this may mean that caches
need to be cleared. If this happens, the exact error is logged and
can be seen in the JOSM status report.
This might not appear with the production key (testing was done with
a custom API key)
