On non-Mac OS system, use xdg-open in browse-url if available

This allows the usage of freedesktop.org's xdg-open which is present
on basically any Linux and BSD system nowadays.

Another slight improvement is that on Mac OS X, /usr/bin/open is tried
first, so no icon pops up in the dock due to the JVM switching to
becoming a GUI app (unless it was a GUI app before browse-url was
called).

This patch has been tested on the following OSes, all with
1.6.0_<something> JVMs:

Mac OS X 10.6.8
Windows XP SP3, both from CMD.EXE and in a Cygwin bash shell
Ubuntu Linux 10.04 LTS

The test consisted of the following commands typed into a REPL, run
inside the Clojure root directory where readme.txt and epl-v10.html
files are:

(use 'clojure.java.browse)
(browse-url "http://www.yahoo.com")
(browse-url "readme.txt")
(browse-url "epl-v10.html")
