FastCGI support

The manager is now natively written for FastCGI. Portal will follow in 2.0

LL::NG Portal can be used under a FastCGI system very easily. You just have to load LL::NG FastCGI support and write a loop in the CGI. Example with the portal:

#!/usr/bin/perl
use Lemonldap::NG::Common::CGI qw(fastcgi);
use Lemonldap::NG::Portal::SharedConf;
# ...

LMAUTH: while ( my $portal = Lemonldap::NG::Portal::SharedConf->new({}) ) {
    # ...
}
