Subject: [PATCH] Add support for unprotected unix socket

 - You can now provide a unix socket based redis connection:
   - `Resque::setBackend('unix:///path/to/redis.sock')`
 - username/password/db in unix socket dsn currently unsupported:
   - This middle layer for Dsn parsing seemed too clunky for me to introduce user/pass/db parsing for unix sockets.
