This updates a preference's value both in the systempreferences table and in
the sysprefs cache. If the optional parameters are provided, then the query
becomes a create. It won't update the parameters (except value) for an existing
preference.

This deletes a system preference from the database. Returns a true value on
success. Failure means there was an issue with the database, not that there
was no syspref of the name.
