style-mode: Make it rememberable again.

It was made non-rememberable to avoid auto-mode reactivating it automatically on
browsing when it was manually disabled.

Now that we have toggle-modes with an action to disable auto-mode in the
process, it's more convenient to toggle modes and override auto-mode's
behaviour.

Thus we can make style-mode rememberable again.
