My WinAos and LinuxAos version for spasim Render.Mod

Spasim (Render.Mod) now works on windows and linux using common OGLWindow.Window object. 

- OpenGL related files are revised.
- Render.Mod is converted to OGLRender.Mod

 *.Obj files and some source files which are in linuxaos/source tree are removed.
  Building for WinAos and LinuxAos is defined in  Spasim.Tool
