Small refactor for followers/friends, change display to use tabs instead of "leaky brains"

Closes #111

First and foremost checkbox in #215 (closed)

• Friends/Followers-related code removed from Timeline component/statuses module and moved to User Profile component/users module.

• Stores follows/followers in user object instead of timeline. Currently doesn't clean up on exit, but checks if there already fetched data available.

• Timeline now has another property embedded which disables panel classes, making timeline easily embeddable within other components.

• Small display fixes for relevant parts.
