New port: textproc/redland-bindings - Language bindings for the redland rdf library'

The Redland RDF parser package (textproc/redland) recently
forked into two packages -- one for the core library, and
another for the bindings for various languages. This port
is for the language bindings for redland.

The textproc/redland port may itself have to be updated/changed,
as redland-bindings requires librdf.la to build the Java
component (possibly Ruby or TCL too, unable to test), and
this is not installed by the textproc/redland port currently.
I will work on a new redland port soon.

The OPTIONS part of this port could probably be improved
by somebody with more knowledge on the subject than I (this
is my first attempt at writing a port), but I see that there
are fairly recent discussions on the mailing lists regarding
using OPTIONS together with WITH_ -> USE_

I will be actively using this software on FreeBSD for a
number of years to come, and will happily act as the port
maintainer.
