Make the 'Forms' compatibility library 'fltk_forms' optional

Browse Source 
This library is no longer needed in FLTK itself. There is only one
demo program (test/forms.cxx) that uses it if it is built. The demo
program displays a message if fltk_forms is not available.

The default is 'enabled' for backwards compatibility but this may
be changed to 'disabled' in a future version.
