Changed search function of Treatments page:

Deleted "Include all treatments in search?"; searches are now never limited by citation.
Deleted Search button: search results are updated as you type.
Restored case-insensitive matching (as it is in MySQL by default).
Search terms now match if they match any substring of the name or definition column values.
Made search term box sticky: your term doesn't get erased as soon as the search commences, and focus stays in the box.
