Merge trunk HEAD

It's the last time I Merge. At Olivier's request, I just tested the webhelp addon. It works like a charm :)

To test I used:
ofbiz trunk svn release 1442197 (as Olivier requested, I guess HEAD would have worked as well)
last addon manager (I used  addonmanager-20130225.jar taken at http://code.google.com/a/apache-extras.org/p/ofbiz-adm/downloads/list)
adm install org.ofbizextra.content.webhelp (following http://markmail.org/message/p4k4yvwct4rql5js)
ant load-demo (or seed, ... data have to be loaded)
ant webhelp

Then test on localhost (with FF you need to allow popups for localhost ) humanres et manufacturing (en de ou nl) and accounting editTaxAutorityAssoc to see a specific redirection message

It's great to see it working OOTB without any issues. I believe the tool (addons in general, webhelp addon is still a WIP) is ready for a wide spread use :)
