Logout button

I have two feature requests:

1 - Add the ability to restrict access to albums/galleries to individual users instead of just groups. I have galleries that are only for individual clients to see and thus need to be tied to a particular user and not any group.

2 - It would be nice to have a logout button on the main page instead of having to go into setup and then logout. I also get a weird issue when logging out. Everytime I logout (it doesn't matter what user I am logged in as) I am automatically logged in as guest and must logout again as guest to return to a not logged in status.
