TradeShips.lua takes far too long to process things, it requests vast volumes of space to analyse.
Reduce the maximum and ensure the minimum distances requested of GetNearbySystems so no more requesting 67.7 light years worth of systems!
Also start with the half-distance and use it if it is acceptable, only go further if it's not.

As the other improvements have highlighted it seems we might need some more profile logging in the GasGiant code.
Initialize m_hyperspace on load (hopefully fixes #2847).
Disable the save button when in hyperspace
