FLTK recipe

When making a new recipe for Alsa-Tools (I don't think I need it, but
just in case someone needs it...), it failed to compile because it
needed FLTK.

Problem is that we still have listed versions for 2.x versions, that
according to the website, are 'Older Abandoned Versions' and should
not be used.

"When new users discover FLTK, they are immediately confronted with
the choice of which version to use, and because they don't know all of
the history, they mistakenly assume that they should download the
higher numbered versions. To make life simple, new users should only
choose either FLTK-1.3.3 (stable) or FLTK-1.3.x (development)."

Can these 2.x version entries be removed from the recipes list?
