Direct mySQL queue does not allow you to specify port

[Bertrand Fan]

gearmand allows you to specify almost all the same settings for mysql as libdrizzle, but it does not have a port setting (e.g. --mysql-port)

MySQL:
  --mysql-host arg (=localhost) MySQL host.
  --mysql-user arg MySQL user.
  --mysql-password arg MySQL user password.
  --mysql-db arg MySQL database.
  --mysql-table arg (=gearman_queue) MySQL table name.

This is in gearmand 0.34 and trunk as well.
