New OS X nightly

[Yllier123]

Hi
I've finally managed to (slash got round to) build VDrift properly for the first time since around July or whenever the gettext stuff was added, so I thought I'd put a nightly (bit of a misnomer really, isn't it?) up: http://sourceforge.net/projects/vdrift/f...g/download (use svn revision 1271).
I tested it on clean 10.7, 10.8 and 10.9 virtual machines, so it should work on those systems. 10.4 is definitely not supported anymore - SDL2 doesn't support it. 10.5/10.6 aren't tested - I know I've had a bug report from 10.5 which I don't think I've fixed yet. I even tested the Xcode project very briefly - so that may work for other people as well!
