let user choose web port

Currently WordPress is available on port 8080, we should probably give users the option to choose a different port (80 would make sense for production environments)

Simplest thing to do is just have the WordPress container run on port 80 instead of 8080 (might need to update some rewrite rules and proxy rules that refer to 8080). Configuring all ports for all services is a nice idea, but not necessary.
