[PATCH 1/2] Build java and ruby versions of core gem

[Ben Browning <bb...@redhat.com>]

The Rakefile was modified so that 'rake gem' or 'rake package'
builds both the java and ruby versions. If you manually run
'gem build deltacloud-core.gemspec' then the version built
will depend on which interpreter you're using.

The java gem doesn't include eventmachine, thin, or rerun. The
deltacloudd script will need to be modified to run under jruby.
