Feature idea offline mode

[ianorlin]

If I was using mup to preiview sphinx documentation or soemthing similar should see how it ends up being rendered if it is offline documentation. Could be --offline or seomthing if you are writing and want to see how it works and not exactly disconnected from the internet yourself. This would also change the _openurl in mup/mup view.py

Do you mean having MUP running the command necessary to rebuild the Sphinx doc when the current .rst file change? That could be useful, but I'd have to figure out how to make this easy to set up in the UI since it would mean configuring a converter for a specific document, rather than based on the file extension.
