[z3-five] default view name

[Philipp von Weitershausen]

Hi there,

when an object is traversed in Zope 3 and no view has been provided 
explicitly, the traversal machinery will look up a view according to the 
default view name for that object. zope.app by default sets this value 
to 'index.html', so that for all objects, by default,  the 'index.html' 
view is looked up when no view is specified. This behaviour can be 
changed for every interface individually.

Five emulates this behaviour when you have marked a class with 
<five:defaultViewable />. This is good. However, Five doesn't set a 
default view name. IMO it should to be as much compliant with Zope 3 as 
possible.

If noone objects, I'll add a

   <browser:defaultView name="index.html" />

to Five.browser/configure.zcml.
