Merge lp:~shevonar/widelands/opengl into lp:widelands

[Shevonar]

This branch improves the OpenGL rendering:
- gameview is split into two subclasses: gameviewSDL and gameviewOpenGL
- terrain edges are dithered and rounded in OpenGL mode (via a texture mask)
- minimap is shaded correctly
- road textures should be fixed (resized to 64x64px)
- Made OpenGL the standard renderer and remove * highly experimental * from options menu
- fixed bug 649037
