[Isugamedev-midworld] OpenSG branch merged with the head

[Ben S. <bs...@vr...>]

I've finished the initial iteration of adding OpenSG support into 
Midworld. As such, I have take the code on the branch I've been working 
on (opensg-branch) and merged it in with the HEAD. Thus, you will now 
need OpenSG 1.1.0 (http://www.opensg.org) to build Midworld. Remember to 
make sure you use g++3 when you build OpenSG (see 'configure --help' for 
details).

[Yes Levi, there is a downloadable binary of OpenSG for Win32].

On a side note I've updated the resources.zip file online to include 
some test models, so you'll want to re-run get-resources.sh.

cheers,
