Side by side rendering

- Side by side rendering implemented throughout the graphics pipeline.
- New GuiTSCtrl renderStyle property is set to "stereo side by side" to
activate.
- You set an IDisplayDevice on the GameConnection to define any vertical
FOV, projection offset, and stereo eye offset properties required for
the stereo rendering (no display device included with this commit).
- Full and Empty templates updated with correct scripts and shaders.
