made rhodecode work with celery 2.2, made some tasks optimizations(forget results) added celeryconfig.py with just the definitions of hosts, it seams just this is needed to get celery working nice, all other config options are taken from .ini files. This is a temp workaround until i get the proper soltuion to this problem.

## Broker settings.
BROKER_VHOST = "rabbitmqhost"
BROKER_USER = "rabbitmq"
BROKER_PASSWORD = "qweqwe"
