Subject: [PATCH] Adds -r flag to resque-web for redis connection

-r or --redis can now be used to specify the
redis connection string.

TODO: A string like redis://:secret@localhost is encountering an
error, even though it works in irb doing:

irb> require 'redis'
irb> r = Redis.connect(:url => "redis://:secret@localhost")
 => #<Redis client v2.2.2 connected to redis://localhost:6379/0 (Redis
 v2.2.12)>
