PATCH: java.util.List and java.util.Set implementation for Clojure native collections

[Meredydd]

See attached, a patch against current SVN head (rev 951) which makes native
Clojure vectors and sequences implement java.util.List, and sets implement
java.util.Set. Also see attached a mini test script.

The second patch, which is dependent upon the first, alters the RT.print()
function (aka (pr)) to print all java.util.Sets in #{...} reader notation,
and all Lists in [...] notation. Native Java maps are also printed in {...}
notation.

I think implementing the Java Collections sub-interfaces (List, Set,
Map) is a good idea for Java interoperability, even if they have to be
read-only.

I've made vectors implement List and sets Set. List is a very poor
match for non-indexed sequences.

As far as Maps, unfortunately the collection API design precludes a
class implementing both Collection and Map (conflicting remove
signatures). All Clojure collections implement Collection. Making maps
implement Map would be a breaking change.
