EventDelegate/Content property usage improvements

- Remove pointless confusing aliases for avatar properties
  (smallAvatar, collapseAvatar, etc)

- Make some EventDelegate properties readonly as they should be

- Use Layout.preferredWidth/Height for avatarWrapper instead of both
  minimum and maximum W/H
