`Navigate` component

[Archmonger]

For event driven applications, it is useful to be able to dynamically route to different paths.

@component
def example():
 redirect_handler, set_redirect_handler = use_state(None)

 def click_event(e):
 resp = check_some_api()
 if resp.status == 501:
 set_redirect_handler(navigate("/login_incorrect"))
 elif resp.status == 200:
 set_redirect_handler(navigate("/login_successful"))
 else:
 set_redirect_handler(navigate("/login_error"))

 return div(button({"onClick": click_event}), redirect_handler)

This should be based on the react-router navigate component.

This feature might use our future use_messenger hook to handle redirection events.
