[Zope-CMF] Adding context to FactoryTypeInformation.queryMethodID

[Christian Heimes]

I'd like to change the queryMethodID method of FactoryTypeInformation in 
CMF 1.5 and HEAD. I want to reimplement Archetype's template mixin 
feature for CMF. (*)

For the new feature I need the caller context in queryMethodID for a 
dynamic view template. I propose to alter the method from 
queryMethodID(self, alias, default=None) to queryMethodID(self, alias, 
default=None, context=None) and add context=self to all calls of 
queryMethodID.

(*)
TemplateMixin allows to register different view templates per portal 
type. The owner of a content object can select a template that should be 
used as the default template for his object. For example he can choose 
that a folder should be viewed as photo album instead of folder listing 
by default.

I would be happy to contribute it to CMF 1.5 under ZPL 2.1. Is CMF 1.5 
still open for new features?
