Override some versions needed to get buildout to run:

The constraint, 1.3.2, is not consistent with the requirement,
'plone.app.jquerytools>=1.5.1'.
While:
  Installing.
  Getting section zeo.
  Initializing part zeo.

IncompatibleConstraintError: Bad constraint 1.3.2 plone.app.jquerytools>=1.5.1

I didn't have time to look into where the 'plone.app.jquerytools>=1.5.1' is
coming from so I'm not sure this is the right solution.
