Subject: [PATCH] Introduce hook_islandora_tabs_alter().

Called just before return of drupal_render()'d markup.  Passed the
tabset and associative array of the parameters with which
hook_islandora_tabs() was called; that is:
array(
  'content_models' => {an array of ContentModel objects},
  'pid' => {the PID of the object being rendered},
  'page' => {the page of the object to be displayed},
)
