BGE: Fix for [#34781] "bge.texture.ImageRender does not show Font object" reported by Monster.

This fix is mostly based off of HG1's patch from the bug report, which had ImageRender::Render() call KX_KetsjiEngine::RenderFonts(). However, I have moved RenderFonts() from KX_KetsjiEngine to KX_Scene where all of the other font and rendering functions are. The real fix for this mess would be to not have ImageRender::Render() have so much duplicate code from KX_KetsjiEngine::Render(), but that's a code cleanup problem for another day.
