add ability to only test specific apps

[Anand Kumria]

Hi,

Some Django applications, e.g. ghettoq, ship with a lot of unittests.

In ghettoq's case, there are a number of backends that can be configured and the tests assume that they all will be.

That is fantastic work on behalf of the ghettoq developers but it can make it hard to integrate into a CI environment.

To overcome this problem, ghetto recommends using a testrunner that they bundle.

In this test runner, the setting TEST_APPS, if found, contains the list of applications to be tested.

Below is a one-liner that allows for this.

It also need an entry in the documentation but I believe this would be a nice win for both Django 1.2 and 1.3

Thanks,
Anand

I'm afraid I don't see why this should be a configuration item for the CI tool, rather than the Django app itself.
