Switch from horribly non-shaded jruby-complete to saner dependencies

Especially in the Fiji project, we had tons of reports about problems
with woefully obsolete dependencies bundled in the jruby-complete.jar
file. So let's not use that one.

Should other dependencies be required, we can always add them back
later.
