Failure to check up *3* folders when running the binary from
chrisboulton/php-resque/bin/ results in never finding the autoload
file when it tries to load up the composer dependencies.
* implement a fork helper method that closes the connection to redis before forking (instead of resetting after)
to work around bugs with phpredis/socket fork handling
* phpredis does not automatically typecast to string, so worker name must be typecasted when registering
* recommend php-resque be installed via Composer
* provide quick getting started steps
* move ./resque.php to bin/resque, make it available as a Composer bin
* have classes autoloaded via Composer (or some other means if not using Composer)
