Allow more than one custom user agent

There should be an option in the settings window to add more custom UAs. Attached is my idea of how this will work.

Lemme chime in with my super duper amazing preview powers

I'm imagining the custom user agent customisation to look somewhat like the search engine customisation

and upon pressing manage, a pop up would appear to allow the user to add their own user agents

and when you add the custom user agents, they can just show up in the user agent menu, or perhaps a sub-menu from the Custom user agent
