This commit updates the clj-parent dependency to 0.4.3 and i18n plugin
dependency to 0.7.1. This commit also includes some updates to
i18n-related files, including the removal of pot files which are no
longer used, updates to the Makefile, and regenerated .po files.
Prior to this commit, we didn't actually have any tests that
started a real web server and made a real request. This
commit adds tests that do this for the clojure and Java
synchronous clients, using SSL.
