* adds askbot/media/jslib/htmx.min.js

* bug fix in askbot/startup_procedures.py:test_custom_user_profile_tab
* custom tab setup is working
* adds option to specify a function that determines if a user can see the custom tab, e.g.:
  ASKBOT_CUSTOM_USER_PROFILE_TAB = {
      'NAME': 'My Custom Tab',
      'SLUG': 'my-custom-tab',
      'CONTEXT_GENERATOR': 'myapp.views.my_custom_tab_context',
      'USER_IS_AUTHORIZED_FUNC': lambda user: user.is_authenticated and user.is_staff
  }
