Change to port 50505

[pamelafox]

Purpose

Port 5000 doesn't work well on many Macs due to a system process that uses 5000. You don't even get a port conflict error, it just silently fails to load :( I would love to not have to constantly change start.sh when I work on this repo, so I propose my favorite port, 50505.

This PR also removes the command the opens the browser. That command opens the browser before the app starts up, so you end up having to reload it anyway, and you have a moment of thinking it's broken. I think it's better to just click on the URL and open it once it's running.

Does this introduce a breaking change?

[ ] Yes
[X] No
