All maps with ports should have them a an identifiable layer in the Mission Editor (and scripting engine)

[TEMPEST.114]

In order to quickly find ports on the map, the mission creator shouldn't have to scour the map and write down lat/longs for them.

The maps that have ports detailed and modelled should have them marked and selectable and the mission editor should have a layer showing all the 'modelled ports'.

The scripting engine should also be able to grab a list of ports and get data about them. i.e. max size of ship, number of berths etc.
