of OSX. It was partially caused by 'negative time', or successive
calls to SDL_GetTicks() returning smaller values than previous calls.
This obviously totally confused the timing logic, which was never
designed for time to go backwards. Related to this, setting the
framerate to 0 from the VideoDialog UI (indicating that auto-frame
should be used) ended up setting the time-per-frame to approx. 71
minutes, resulting in a delay of 71 minutes to the next frame
(which is what caused the 'lockup').
Changed all references to the Intel OSX build to also mention OSX
Snow Leopard (10.6), since the build won't run on 10.4 or 10.5.
Bumped version number to 3.1 (again). Hopefully this is good to go.
