Merge transports' nanobots into hull

[NixOlympica]

Transports should not have their regens integrated into their base hull.

Mounting armour on a transport is a risk vs reward choice. By not mounting it you have a little extra space to make profit but the downside is that you will die very easily, particularly to one SNAC. If you use an armour upgrade you lose a little space but are much more survivable. This is how the dynamic should be and how it should remain.
