Defaults: Reduce near-clipping in factory settings

For newly opened 3D Views, the default would actually be 0.01m. But the
code to update the default for all existing 3D Views in the
startup.blend was missing. So the defaults were out-of-sync.

0.01m is the more reasonable default as agreed on by the UI team.
