Simple but powerfull patch to make application name localizable

[Vsevolod Novikov]

The applied patch is used to make application names localizable for admin interface and also for other purposes.

This patch is applied to django v. 1.2.3 (django.VERSION = (1, 2, 3, 'final', 0))

It uses a new APP_NAMES variable from the user-provided settings.py which should be a dictionary having application label (model._meta.app_label) as a key, and application verbose name as a value. If the APP_NAMES is absent or doesn't contain a label of the application, the old schema (app_label.Title()) is used.

This way allows to localize application names exactly as other things in the project:

settings.py:

...
from django.utils.translation import ugettext_lazy as _
...
INSTALLED_APPS = (                                                                                                                                             
    ...
    'myapp.service',                                                                                                                                        
    ...
)                                                                                                                                                              
                                                                                                                                                               
APP_NAMES = {                                                                                                                                                  
    'service':_('Service')                                                                                                                                     
}                                                                                                                                                              

Now the "Service" string will appear in the django.po files for the whole project, so you can localize application names as you wish.

This patch is a minimalistic way to make a part of the job made by the patch published in the ticket #3591. Reasons why I've published the patch is - "simpler means more stable", and "One patch - one job".

All-in-one patch to use INSTEAD of the previously-submitted separate patches

This is very much related to #3591 and this year's Google Summer of Code project about the app loading that deals with the fact that app_labels are used improperly in a lot of places in Django. Translating the app names is one feature included in that branch which is slated to be worked in 1.4.
