[Tom Gidden]

A few changes:

* Added nextWord(): an alternative to parseWords(). As parseWords()
can't be used in triggers due to the use of a CREATE TEMPORARY TABLE
(I think), I've taken the word-chopping bits of indexString() out and
moved them into the new procedure nextWord(), along with a big tidy-up.

* Retooled indexString() to use nextWord(). I haven't really
considered the relative merits of the two approaches, so I've only
used it in indexString() where I know parseWords() won't work.

* Moved triggers into tests/, as they link in with article table

* Moved old article__-specific procedures into sql/old/. If you're
happy with the new non-table-specific functions, we can ditch this
directory.

* Hid spurious warnings in classID and wordID, by using a handler.
