Back-ported cut & paste code from fltk2.0.

This code splits the cut & paste into two buffers. The "SELECTION" is
used for the currently highlighted text and for middle-mouse paste and
(if possible) for handling drag & drop. The "CLIPBOARD" is for Ctrl+C
and Ctrl+V style cut & paste.

This matches how Motif, GTK, and KDE 3.0 work. But many older X
applications (including KDE 2) can only see SELECTION, this results in
cut & paste incompatability that is familiar to X users. However this
now moves fltk over to the majority camp.  On all systems this
eliminates the annoying inability to select a region and replace it
with Ctrl+V.

On Mac and Win32 the SELECTION is local to the application, so
middle-mouse paste only works between fields in the application. There
may be tricks (special clipboard data types? use drag & drop?) to make
it communicate, but unless there are standards it would be fltk-only.

The file Fl_cutpaste.cxx has been deleted, so update the IDE files!
The Win32 and Mac versions have NOT BEEN TESTED! I tried to be careful
editing them but they may need some work.
