Revert "Add settings for custom compendium URL"

This reverts commit 53ff4f1eed2619a00d9a353d42e0a28070d6025c.
Combat manager can now use alternative URL for compendium

If they ever change the url of the compendium, I bet they change the
search parameters too.  The item finding part is what I would add if I
were writing the compendium...an exact name search.
