Include port in console run hint

[rafraser]

This PR adds the --port argument to the run hint provided by the Textual dev console.

Unfortunately, something I'm working on also uses port 8081, so whenever I'm using the Textual console I'm always using a different port. This is a pretty minor addition but it'd make things ever-so-slightly easier for me!

Good idea. Just a request for a docstring. We like everything to have docstrings, even if it occasionally seems redundant...

[willmcgugan]

Docstring please!

[rafraser]

Done! I also added a docstring to the DevConsoleHeader class to match the other renderables in the file

I've stumbled over the same problem. Currently I'm using the pull request sources to use the --dev mode but would like to switch back to the regular version as I face problems with 'textual keys'.

This PR displays the port, but it doesn't implement the --dev switch which has existed for months. What problem are you having with textual keys?

This was misleading... I wanted to refer to the --port-option. When using the this branch and starttextual keys, I get the following stacktrace:

Well, sorry, my fault.
