Spoike 93aba48cdc TA couple of fixes. 
Meshes now have the right lighting if they were cached before rendering.
npFTE startup/shutdown/restartup is more robust and is less likely to crash browsers.
Re-added the r_shadows cvar. It now provides blob shadows.
Hopefully fixes mingw voip crash, may need mingw upgrade, sorry in advance moodles.
