Expand debian/copyright per Luca Falavigna's feedback.

debian/copyright: convert to machine-readable DEP-5 format and note that
licensing isn't entirely uniform (but that most exceptions pertain to
convenience copies of libraries that Debian builds refrain from using).

+ The FLTK library and included programs are provided under the terms
+ of the GNU Library General Public License (LGPL) with the following
+ exceptions:
+ .
     1. Modifications to the FLTK configure script, config
        header file, and makefiles by themselves to support
        a specific platform do not constitute a modified or
        derivative work.
-
+       .
        The authors do request that such modifications be
        contributed to the FLTK project - send all
        contributions to "fltk-bugs@fltk.org".
-
+       .
     2. Widgets that are subclassed from FLTK widgets do not
        constitute a derivative work.
-
+       .
     3. Static linking of applications and widgets to the
        FLTK library does not constitute a derivative work

        FLTK libraries, or link their applications or
        widgets against a user-supplied version of FLTK.
-
+       .
        If you link the application or widget to a modified
        version of FLTK, then the changes to FLTK must be
        provided under the terms of the LGPL in sections
        1, 2, and 4.
-
+       .
     4. You do not have to provide a copy of the FLTK license
        with programs that are linked to the FLTK library, nor
        do you have to identify the FLTK license in your
        program or documentation as required by section 6
        of the LGPL.
-
+       .
        However, programs must still identify their use of FLTK.
        The following example statement can be included in user
