- API: add BOINC copyright notice to graphics2_win.cpp. 

This file originally used code from the following tutorial,
    which shows how to open a window using GLUT:
    http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=01
    The code has now been completely rewritten;
    in particular, it doesn't use GLUT anymore.
- scheduler: change default limit on #CPUs from 16 to 64

- API: add BOINC copyright notice to graphics2_win.cpp.
This file originally used code from the following tutorial,
which shows how to open a window using GLUT:
http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=01
The code has now been completely rewritten;
in particular, it doesn't use GLUT anymore.
