[Bug] Sanitizing institution data harvested from GrSciColl breaks functionality

[mickley]

In the institution editor, there is now a call to sanitize all institution data before displaying it using htmlspecialchars(), see:

Symbiota/collections/misc/institutioneditor.php

Line 201 in 06f6cb6

$instArr = $instManager->cleanOutArray($instArr);

That seems reasonable, however, when I wrote the code to harvest data from GBIF's GrSciColl API, I incorporated several GrSciColl/indexHerbariorum fields and links to Index Herbariorum and GrSciColl in the notes field, using some html. Santitizing with htmlspecialchars unfortunately breaks that functionality. See:

Symbiota/js/symb/collections.grscicoll.js

Line 297 in 06f6cb6

// Add taxonomic coverage to notes, if included

Here's what it should look like:

Here's what the sanitizing does:

@Atticus29: There's different ways this could be fixed: sanitizing all except the notes, allowing limited html, having more institution editor fields to avoid this need, etc. Up to you as to what works best.
