Clean tests after refactoring step for Oozie message body rewriting support.
Refactored Parser to handle "naked" authority URLs (e.g. host:port).
Add new method to Template/Builder/Parser to distinguish between special "naked authority" URL and a normal one.  This ensure that the templates for //host:port and host:port can be distinguished.
Enabled now working Oozie test.  Oozie body still being handled transparently.
Cleaned up some I18N messages and resources.
