Some Quartz initialization scripts have comments in a different format.

This commit introduces a `comment-prefix` property that should be set by
the user if their target database has a script that contains those
unusual comments.

Previously, when an empty String was bound to a collection or
array of rich types it would fail as there was no converter capable
of creating a Collection<RichType> or RichType[] from the String.

This commit updates IndexedElementsBinder to apply special treatment
to empty String values. Now, when such a value is being processed,
an empty Collection or array is the result.
