Resurrecting the Mac build

[hiran]

If you are getting familiar with the code maybe you could have a look at game startup.

On Windows and Linux you can run

oolite -load <savegame>

and Oolite would load and start that savegame. It does not work on the Mac version but is an important feature for using OoliteStarter. I suspect the root cause is there are two different entry points that support different parameters.

Maybe it would be good to file an issue on github so that things like this are not lost in forum thread. Also, this perhaps may depend on solving the OpenGL issue on top of trunk first.

That makes sense. Unless we get Oolite built on Mac this issue is void. I'll file it on Github.
