Custom method for Model to simplify getting formfields

[vsevolod.solovyov@…]

This method will simplify creating of complex forms. Now it's clear what fields belong to what models.

class BookmarkForm(Form):
    url = Bookmark.get_form_field('url')
    title = Scrapbook.get_form_field('title')
    description = Scrapbook.get_form_field('description')

Instead of:

class BookmarkForm(Form):
    url = forms.URLField(max_length=200, verify_exists=False, label=u'URL')
    title = forms.CharField(max_length=256, required=False, label=u'Title')
    description = forms.CharField(required=False, label=u'Description', widget=forms.Textinput())

If patch itself is ok, I'll write documentation and tests.

Thanks for the patch, but I don't think this is worth including. Putting one model after another in a form like this is only one of many cases and we can't have special methods for every case. If anybody wanted to do this, it's only one line in their code in any case.
