Automatic stripping textual form fields

Here is a class decorator that allows not to bother with stripping leading and trailing white space from user input provided via forms. This could be a temporary solution for an issue addressed in the ticket [#6362](http://code.djangoproject.com/ticket/6362). The documentation is provided in the form of doctest. The decorator works with `ModelForm`'s just as well as with ordinary forms. Note however that this is not a 100% panacea. Your models still could become malformed if theirs data is obtained from another source, not forms.

Enumeration field

These three classes allows you to use enumerations (choices) in more natural model-like style. You haven't to use any magic numbers to set/get field value. And if you would like to make your enumeration a full-fledged django-model, migration should be easy. Note, that you can subclass Item to add some context-specific attributes to it, such as `get_absolute_url()` method for instance. Examples are provided in the form of `doctest` in the second half of the snippet.
