Apache Forrest code update (bug FOR-800)

code update
by
TS
(fixes bug FOR-800)

:

Make
forrest.properties.xml (as aggregation of all properties) available via cocoon:// protocol.
The last remaining issue was implementing the Iterator getAttributeNames in the
ForrestConfModule. To see all available properties add
org.apache.forrest.plugin.output.inputModule and request
cocoon://module.properties.properties.
