Show Name - combine lookups for classification links

[nimmolo]

The "Classification" panel does 14 separate lookups of Names to show the links to the "parent" taxonomies. It costs the page about a second of load time.

  Name Exists? (27.6ms)  SELECT 1 AS one FROM `names` WHERE (`names`.`correct_spelling_id` IS NULL) AND (`names`.`search_name` = 'Grifola') LIMIT 1

Those lookups seem like they could be consolidated into a single mother query, with the names derived from that query.

This reduces load time for the Classification partial from 768ms to 207ms locally, a 73% savings.
