Generate user-agent string [Feature Request]

[Tahlor]

I think I need requests to have the same user-agent string as my browser to re-use the cookie on some sites.

If this is the case, it would be nice if the module could get the user-agent string of the browser. Is there an easy way to get the user agent string without opening the browser? If someone knows of one, I'd be happy to implement it.

I know you can get the version of Chromium by running chromium-browser --version, not sure of the best way of how to translate this into a user-agent string though.
