First version of "near" airspaces and their widget from side. #466

This version uses floats to compute distance to airspaces of pilot.
In an improved version, we can switch to int32, which is faster.
However, I would like to PR this version first, to discuss overall
design and implementation.

AIRSPACE_CACHE_VERSION has been increased, as we set brush and pen color if missing on parsing. Therefore cache version must be updated.
