[patch] Added "length" param to Field class

[robert.morris@…]

Pretty much what the title says: I wanted to be able to specify the "size" attribute of form field both in the admin interface and in views using manipulators. My ​post in django-users in ​an old thread on the issue stirred up a "yes it's goofy -- make a patch" suggestion. So I did.

First patch submission, so I hope I did it right :)

Modified to take a "length" parameter, used in "size" attribute of HTML form fields

[robert.morris]

TODO: make a comprehensive list of the field types that this can be used for; I initially thought that it would be valid for any field type subclassed from TextField, but that's not always true. IntegerField, PhoneNumberField, and USStateField are at least some field types that don't specify the length keyword, even though they are subclassed from TextField.

I'm voting for this option as well.
It'll make the Admin screens more flexible and useful.

Before this can go into the tree, the TODO item from a couple of comments ago needs to be fixed (probably any field taking a maxlength attribute can also take size) and there should be a patch to the documentation (docs/model-api.txt) as well.

accepted as per Adrian's comments on the mailing list thread.

The newforms library exposes the ability to do this, I believe, in which case this is fixed.
