[TIP] removing attributes and dictionary keys using mock.patch

Hi All,

I'm excited to see how far mock.patch has come, mainly as I'm hoping I 
can deprecate testfixtures.Replacer as a result ;-)

The only think it looks like Mock can't currently do is remove 
attributes or dictionary items:


Michael, would you be up for me adding that to Mock or is it a non-starter?

I'd be happy to approach using either a delete=True option to patch() 
and patch.dict() (I don't really understand what patch.object does, so 
can't comment...) or, alternatively, a not_there or deleted marker 
object like I did in testfixtures.

Lemme know your thoughts...
