Short (oh no, bikeshed alert..!) naming question:

I'm about to checkin some changes in grokcore.view and grok that will:

1) split off the response property and the url() and the redirect() 
methods from grokcore.view.View into a separate "mixin" class.

2) split off the application_url() method from grok.component.View into 
a separate "mixin" class.

That way JSON and XMLRPC and REST components can inherit from these 
mixins and thus gain all the mentioned methods.

Now, what do I call these mixins?

So far I came up with "ViewCommonMixin" for the first. Ugh. And 
ApplicationCommonMixin. Ugh Ugh. Anyone a better idea?
