[Feature Request] Display IP of octoprint.

[JamesM92]

Is your feature request related to a problem? Please describe.
-I have a octopi at my employer with octodash, but if the IP address changes there is nothing on the dash to tell me what the IP address is, and octodash took over the screen quickly making it hard to catch the IP address.

Describe the solution you'd like
-Give a location in the settings menu to show what the current IP address of the octopi is encase the IP has changed regardless of any changes.
