Added Copy and Paste functions to GHOST.

- Moved WIN32 code to ghost and added code for other systems.
- Added functions getClipboard(flag), and putClipboard(buffer, flag)
    -Flag is used on X11 to request selection buffer or clipboard.
    -If any other system uses flag = 1 the function returns doing nothing.
- Changed ctrl +c/v and shift+ctrl + c/v to do the same thing (use the clipboard).
- Changed the menu items (copy, paste) to use the clipboard.
