PATCH: Add an option to disable deactivating region hilighting whenever you edit something

[Mikael Magnusson <mikachu@gmail.com>]

For allowing zle beep to end the region, you could just use REGION_ACTIVE=0 instead.

While we're on the topic of deactivating the region, I've had this patch lying around forever in my local tree, but never cared enough to send it. It just keeps the region on until the user disables it again, I use this very complicated widget:
  _toggle_region_active () {
    (( REGION_ACTIVE = !REGION_ACTIVE ))
  }

My use case for the above is doing a set-mark-command, typing a long thing, and then invoking quote-region, while maintaining visual feedback of the region. (Sometimes I forgot to do the set-mark-command and ended up quoting the whole line).
