Version 1.666 BETA 2

Released version 1.666 BETA 2. A lots of fixes and improvements. I found what slows it down and now it’s a lots faster. But the main is that now it also has OpenGL support. It’s selectable from command line with parameter -opengl. In Windows version everything works. I also created driver for LINUX, but it’s not tested and by default LINUX version compiles without OpenGL support.
