[patch] Incorrect URL_VALIDATOR_USER_AGENT due to DRY violation

[James Wheare <django@…>]

Patch for django.conf.global_settings.py that keeps the URL_VALIDATOR_USER_AGENT setting string in line with the Django version number.

Having the settings file import anything even slightly complex (like management.py) is probably a bit risky, since if any other module is imported indirectly that uses settings, they can't be changed any longer.

So the idea is correct, but we should do the version compositing some other way. Pushing get_version into django/__init__.py might be better.

Moves get_version to django/init.py

Trac seems to munge the diff a bit (take a look at the original format), and I'm not sure if it's better to import django then call django.get_version() or import the method directly, but ​here's a stab.

Looks good, James. Thanks. I'll commit this in the morning (when I'm more awake and can read it again).

[Malcolm Tredinnick]

Hmmm... note to self: we should import get_version into the namespace of management.py so that any existing code doing from management import get_version will continue to work. I'll fix that when I commit.

Django version number. Thanks, James Wheare.
