Vega Strike Code

Updated with some more relevant instructions. Taken straight from newly created wiki page.

Removed deprecated files.

A few optimizations for quick&dirty savegame loading - this allows fast summaries, so that clicking on a savegame doesn't take ages.
Two modes, of which the quickest is the default:
a) Slow but functional: faster than the previous (quite), as it does not load (but merely skip) unrequested mission data.
b) Ultra-quick: does not load anything else than the first line, making it a lightning-fast summary, but cannot be used to compute the campaign score (only drawback, actually) - this is the default.
Config variable available to choose among the two.

Group cell_has_recursive_data, for common field groups.
Should make spawning somewhat faster (in the absence of IO-intensive ops).

This should remove the nasty "wild wobble" bug during startup.

Fixed missing texture tag, turret orientations, and engine size.

Chris' greeat nearest hostile key effort. saves me the work that it would have required...

Prelim ox model, untextured, for testing purposes.

ox_new.blank added. Everything is almost in place, just need some stats tidied.
