Bug 418954 - Add a separate entry combo for port numbers
Adds a new EPortEntry widget which appears alongside "host" entry boxes so users don't have to know about the "host:port" syntax to specify a custom port number. Currently only used in the mail account editor, but we'll generalize it futher so it can be used everywhere.
