a plan how to deal with it.

demonstrates a bug in the very same: The local variable bag was kept
when a new scope was opened, hence it could be polluted by lower scopes.
Zope 3 makes a copy of the local variable bag when it starts a new scope.
This is there Right Thing(tm) to do. This test is now identical to its
Zope 3 equivalent.

hacks that were in there before.  Tried to reduce the diff to the Zope 2.9 code
a little and moved some content type guessing code to PageTemplateFile where it
really belongs (that also avoids a circular import problem).

zope.pagetemplate.pagetemplate.PageTemplate, we need to provide some Zope 2

in Zope 2.10 now, so we could just as well register it here. Gets rid of some
stupid code duplication in Five as well...

* Made ZRPythonExpr subclass the one from zope.tales.pythonexpr.
* Made Expressions use ZRPythonExpr instead of the standard one
  from zope.tales.pythonexpr.
