Feature request: add a way how to reload configuration without restarting browser

[sleep-walker]

For implementing stuff in user configuration it would be handy to have a way, how to reload the configuration.

For example, I realize that some page is worth of defining new webjump, I open editor, add it and then I'd like to get this webjump loaded with the rest of configuration so it's available already within the session.

I implented eval command in a similar way like it is in Emacs so I can add webjumps or commands on the fly but it's still duplication of the effort and clean way would be nicer.
