Write the functional tests for MEDIUM prio scenarios fro the publication workflow.

Scenarios

• Publish single page on root level
• Publish a nested subtree incl. children
• rejection of workflow
  • rejection works
  • editor is notified"

Note 1

The scenario descriptions are prepared - but they are on a separate branch.

(Because when it was created, somebody else worked on HIGH prio scenarios and tests already).

Note 2

We must tackle / resolve MGNLTEST-160 - before these test can be done - because in some of the scenario we switch the user (logout/login).
In the high prio tests we have been "worked around" this by using the same user - but here - i propose - we should insist in swapping the user - especially on the scenario "Rejection of workflow".
