Adds new feature to dispatch avatar url between different servers.

Browse Source 
That allows parallel download from most browsers.
To avoid caching issue, server choice is "profile_id" based so that
avatar from a specific user will always be served from same server.

Introduce new configuration parameter:
$config['avatar']['server_modulo'] = 5;

Very easy to implement using, for example, DNS wildcard.
For example, if you have following configuration:
$config['avatar']['server']        = 'static_rrdns_.domain.tld';
$config['avatar']['server_modulo'] = 5;

Then, when building avatar's URL, domain will become, depending on profile_id:
static0.domain.tld
static1.domain.tld
static2.domain.tld
static3.domain.tld
static4.domain.tld
