Fix for Tomboy indexing

[Larry Reaves <larry moonshinecomputers com>]

Attached is a simple patch to fix a bug in the Tomboy indexer.  After
the initial installation of Tomboy, there is no Backup Directory created
until a note is deleted.  These changes enable it to work without the
Backup directory and, if it is created, starts to watch it too.  Patch
is against current CVS.
