lift the required call to super() in grok.Container subclasses that override __init__

[Martijn Faassen]

When you subclass from grok.Container, it's very natural to do something like this:

class MyContainer(grok.Container):
     def __init__(self):
         self.foo = 'bar'

This will fail with some obscure error concerning SampleData (of all things. Martijn's rule: in code, never call anything 'Sample', or 'Simple', or you'll regret it).

To solve this, you need to call super in your own __init__:

class MyContainer(grok.Container):
    def __init__(self):
        super(MyContainer, self).__init__()
        self.foo = 'bar'

We need a grok.Container which doesn't have this commonly surprising requirement.

While this would be desirable, this would be non-trivial to fix and the work is therefore deferred to post 1.0.

In addition I am not sure whether this is desirable. It is a standard Python idiom that you have to do a super call if you override a method and want the code in the super method to be executed.
