Added stfl library.

Since it will be removed from the portage, because of the breakage on
the latest python version, I've added "new" ebuild, which removes all
the bindings from it, just to not have to deal with it in the future.
The only application which is depending on this lib is newsboat, which
as far as I can tell, doesn't use the bindings.

+		STFL is a library which implements a curses-based widget set for text
+		terminals.
+
+		The STFL API can be used from C, SPL, Python, Perl and Ruby. Since the
+		API is only 14 simple function calls big and there are already generic
+		SWIG bindings it is very easy to port STFL to additional scripting
+		languages.
+
+		A special language (the Structured Terminal Forms Language) is used to
+		describe STFL GUIs. The language is designed to be easy and fast to
+		write so an application programmer does not need to spend ages fiddling
+		around with the GUI and can concentrate on the more interesting
+		programming tasks.
