function sarnia_menu_alter in Sarnia 7

Implements hook_menu_alter().

This totally sucks, but if we want Field UI forms to live under the "Sarnia" tab of Search API server pages, this is what we have to do.

Field UI hard-codes entity and bundle names into the menu array, or else it requires that they be present in the path. Also, the Sarnia tab path plus the Field UI field paths are longer than Drupal's limit of 9 menu arguments.

Moving Sarnia bundle field management to somewhere else in the menu system would mean we could remove this entire hook_menu_alter() implementation, but for now it is more important to keep the UI in one place.
