This is the first release of Profile Tabs with the following features:
- all profile categories that announce themselves to hook_user get their own (secondary) tab (this includes all categories from profile.module).
- Initially the 'account' tab is displayed by default.
- The default tab can be set in 'admin/settings/profiletabs'.
- Profile categories that do not announce themselves to hook_user, are put onto the default tab (e.g. privatemsg's 'PM this user').
