already existed. As a result, 'maven javadoc' would fail if it didn't
already exist. Rather than doing yet another <mkdir> in the javadoc
plugin, I've created an xdoc:init goal that creates the directories.
Any plugin that requires the use of those directories should make this
goal a prereq. I'll be going through all of the plugins to make this
change.
