Add sync_translation_fields

[GoogleCodeExporter]

Hi,
I'm switching from django-transmeta and found handy the sync_transmeta_fields 
command that allows automatic detection and altering of database when adding 
languages.
So, based on transmeta's command, i've built a similar command: 
sync_translation_fields.
Here is the patch :

Regards,

Obviously the patch is for another issue. I suppose you mean this one instead?

You're true. My bad for the copy/paste fail...

Running the management command without changing the LANGUAGES setting raises a 
TransactionManagementError here. I'm using MySQL.

Yep, transaction management has changed in Django 1.3.
Here is the patch :

The management command is in trunk now. Thanks for your help!

Please note, that i had to pass the connection to db_type in get_sync_sql to 
make it work with Django 1.4. Yet have to check if this breaks anything in 
older versions...
