Simple patch to allow fragments to include other fragments:

Browse source 
%fragment("Hello","header") "..."

%fragment("Hi","header",fragment="Hello") "..."

the latter fragment will include the first one if is invoked.

more than one fragment can be included at the time, just
keep adding fragment="f1",fragment="f2", etc.

this is used to emulate typemaps reuse, where all the
reusable typemap code is put in a fragment static method,
and then it can be included from another fragment typemap
as needed.
