setting "state-cache 0" causes models to load as many geoms with a small amount of geometry each

[Josh Enes]

The state-cache setting causes EGG files to not load properly.
Specifically the problem occurs during the conversion to BAM.

You can see with pstats that when "state-cache 0" is set, the EGG file provided in the repro incorrectly loads as 279 geoms.
With the default setting "state-cache 1", it loads as only 1 geom.

I know this is probably too late to be useful for you, but I just checked in a fix. As it turns out, RenderState::compare_to compared the render attributes by pointer, which only works if the state cache is enabled. I just changed it to actually invoke compare_to on the RenderAttrib. Picked up for the 1.8 branch.
