Automatic setup verbose_name for related fields

[Grigoriy Kramarenko]

In a large multilingual projects often lack the simplest things. To edit verbose_name for related objects occurred in one place.

Before:

class Foo(models.Model):
    ...
    class Meta:
        verbose_name = _('foo')


class Bar(models.Model):
    foo = models.ForeignKey(Foo, verbose_name=_('foo'))

After:

class Foo(models.Model):
    ...
    class Meta:
        verbose_name = _('foo')


class Bar(models.Model):
    foo = models.ForeignKey(Foo)

This patch only works when you specify a class and not a lazy reference to the object.
It also reduces the memory consumption.

The patch uses deprecated APIs so the test suit can't run, but even when updated as below, there are still problems running the tests.

if self.verbose_name is None and self.remote_field and not isinstance(self.remote_field.model, six.string_types):
    self.verbose_name = self.remote_field.model._meta.verbose_name

Sorry, that was meant for 1.8, I'll try to rewrite under master

Bad idea. It's works, but in order to do have to change a bunch of tests.
