pyramid_weblayer 0.8.1

A re-factor of some parts of weblayer for use within Pyramid.

Common / shared utilities for a [Pyramid][] web application. (Some originally
re-factored from the depreciated [weblayer][] micro-framework).

Provides:

* a subscriber to validate incoming requests against cross site request forgeries
* a subscriber that extends the template namespace with a `_()` function for
translating message strings
* an `hsts.force_https` configuration flag to force incoming requests to https
* a `join_to_transaction` function to hang function calls off an after commit hook
* some misc. request properties and utility functions

## Tests

The tests pass using Python2.6 and Python3.2, e.g.:

$ nosetests --with-coverage --with-doctest --cover-package pyramid_weblayer pyramid_weblayer
