[heads-up] merging branch to update our Cocoon to 2013

As seen from the commits and issues, i have finally
succeeded with the updating of our packaged Cocoon.

https://issues.apache.org/jira/browse/FOR-1240
https://svn.apache.org/repos/asf/forrest/branches/update_cocoon_2.1.12

So i hope to merge it soon. Need to take it slowly
because the associated issues have consumed my spare time.
 
Before that i need to deploy the trunk PDF output plugin
once more, and then increment its version because
it now has major changes.

Meanwhile if anyone has time to test the branch,
then that would be good.
