Undockable! Sometimes.

[Taose]

Encountered with the experimental build, but present in master.

During a cargo mission, two deliveries to system x, which required meeting with two vessels. Unfortunately, these vessels have a tendency to park themselves close to planets or other objects of sufficient dominance and docking area in such that the docking area actually overlaps rather than "intersects" should we say.

Logically speaking, the closer to an object you are, the greater the likelihood you should dock with that particular object, regardless of which has the largest docking range. Planets for example can be docked from about 1000km depending on size, while ships are typically much much less, akin to a few hundred meters. At those ranges I shouldn't be docking with the planet but the ship as a matter of preference.

The solution would appear to be relatively simple, upon pressing the d key, check for docking areas if multiple docking areas present, store them all and cycle through to check which one is closest, with a preference to dock with ships rather than planets. So if ship closer than planet and ship dock in range, dock with ship else planet.
