1) images
	old images can't be copied anymore
	SOLUTION: use different images altogether
	- option 1) use an icon library
	- option 2) add the old images as a library
2) check orbeon compatibility notes (see: http://wiki.orbeon.com/forms/doc/developer-guide/release-notes/39)
things that *must* be checked:
 - Deprecation and removal of Java classes
things that are checked:

3) new web.xml has classloader options
 setting some classes to not use the orbeon loader might result in caching and
 therefore in a performance improvement.
- also: remove xforms-jsp and other things we do not use
4) new web.xml has error-page-flow.xml
  create an error-page-flow
5) rewrite properties.xml
- recheck orbeon properties
- make it easy to make the required changes (put them in properties-local ?)
6) rewrite adding js and css to rewrite AND add f:nourlrewrite

AND

6) MathJax 2.0
7) check resourcemanager: timestamping
8) adding more content (also: splitting content and source)
9) separate config for repos
FUTURE:
- check SCSCP support and maybe improve it
- investigate seperate orbeon
