Fixed crash on startup issue

Today we've uploaded a new Blensor version 1.0.17 which fixes the issue when Blensor immediately crashed on startup.

The problem was an error in the startup file. A workaround for older Blensor versions is to use an official Blender version to save a working startup file ( File -> Save Startup File or Ctrl-U ).

The workaround requires the same version of Blender that the Blensor version is based on.
