Loop over various ID_SITE in settings.py

[arthurzenika]

right now for various sites we have to do change settings.py for each site.

It would be nice to loop over a dictionnary or sequence where (for example:

key is ID_SITE & value is APACHE_LOG_FILES

SITES = {'1': ['/var/log/apache/site1.log'], '2': ['/var/log/apache/site2.log'] }
