X11: Optionally copy selection buffer to clipboard (STR 3229)
The new method Fl::selection_to_clipboard(int) enables copying
selection data to the clipboard on X11 if it is set to 1.
This feature was requested by STR 3229 and the implementation was
inspired by an `xterm` feature named "Select to Clipboard" which can
be enabled by 'ctrl + middle mouse button + "Select to Clipboard"'
in an xterm window.
