- only load libraries when necessary (openssl takes 6-seconds to
  60-seconds to require 'openssl' in some cases)
- add update-flatjar target
- make update-jar target invoke a few other steps
- update jruby-openssl
- try to make monkeypatching more obvious and contained
- add locales/en.yml to the jar builds
- don't bother doing 'jar i' anymore, JRuby doesn't even look at the
  manifest index. Just wastes time during the build :)
Fix regression
- Fix quoting (which is breaking the test)
