Add support for venusian.attach()'s depth argument.

[AndreLouisCaron]

If you try to enhance Pyramid features by writing a decorator that applies @view_config() to a function generated by this decorator, Configurator.scan() cannot find this view. For example,

from homemade_rpc_framework import register_rpc_method
@register_rpc_method('label', argument_names=['foo','bar'])
def some_rpc_method(request, arguments):
    return {'some': 'result'}

where homemade_rpc_framework.py contains:

from pyramid.view import view_config
def register_rpc_method(label, argument_names):
    def decorator(f):
        @view_config(route=label, renderer='json')
        def pyramid_view(request):
            arguments = ... # extract from request body using 'argument_names'.
            return f(request, arguments)
        return pyramid_view
    return decorator

See Writing a decorator that returns a Pyramid view in the pylons-discuss Google group for more details.

Robert Forkel mentioned that he had the same issue in cornice and found a solution. Based on his input, I wrote a similar fix for view_config(). It seems to work, but I'm in the process of cleaning up, adding comments and testing.

Thanks! I reimplemented this because I could not figure out what repository your commit was to. In any case, the _depth argument now supplies the functionality.
