FSL for Jena & IsaViz

I'm done with the Jena implementation of FSL, which I am ready to make
public (it's in IsaViz' CVS already).

I've also implemented a version for IsaViz: you can enter an FSL
expression in the GUI, and it will highlight all paths in the current
RDF graph that match the FSL expression. See [1].

In both cases, these are general-purpose FSL engines that can be used in
the context of Fresnel applications but also other applications that
might want to use FSL to refer to elements of an RDF graph.

I haven't made any assumption about how namespace prefix bindings are
declared. They have to be set manually by the client application before
the actual FSL expression parsing/evaluation occurs, thus giving a lot
of liberty to FSL client applications. For the IsaViz engine, it takes
all namespaces declared in the corresponding GUI tab and uses them to
resolve bindings in the expression.
