Installer on new site doesn't take port number if different from 3306
I tried to set-up a CiviCRM install on top of WordPress and the hosting company (Pressable) doesn't use port 3306 for the database. Their port number is 3331. The install script still tried to access via 3306 port although we entered the full ip:port string in the field.
CiviCRM 4.7.13 WordPress 4.9.5
