Expands wants request to class, removes request from classes

[justanr]

Considering just making this the 1.0 release.

Expands wants_request to also work on subclasses of Requirement rather than just functions:

from flask_allows.requirements import wants_request

@wants_request
class OldKindOfRequirement(Requirement):
    def fulfill(self, user, request):
        return True

This adds a __call__ method at the front of the MRO that accepts user and request.

In combination with this change, Requirement.__call__ has been changed to only accept user. This change includes conditional requirements, which now only accept user but still use _call_requirement under the hood to compensate for functions and classes that still expect request to be passed but haven't been decorated with wants_request

wants_request will also become a permanent member of the public API since injecting the request into requirements is still useful for some instances and not having to depend on it statically is nice. _call_requirement will removed in the 1.0 release in place of wants_request

Any chance to get this PR merged and a new version pushed to PyPI? :-)

[justanr]

Sorry to be so radio silent on this. There's been a lot going on in my personal life that's blocked this from being merged. It'll be the beginning/middle of July before I can get back to this.

Sorry guys.
