Allow {url} and {url:pretty} as parts of arguments

This makes commands like `:open web.archive.org/web/{url}` possible.
This commit also adds a no_replace_variables command register argument
that stops the replacement from happening, which is important for
commands like `:bind` and `:spawn` that take a command as an argument.
