[Chuck Hagenbuch]

Quoting Michael Varghese <mike.varghese@ascellatech.com>:

> I made some changes to the vfs_sql schema that will make it more usable
> for Gollem.  I added in 3 columns: vfs_type, vfs_owner, and vfs_modified.  I
> also added more functionality to horde/lib/VFS/sql.php as well.  Email me
> with any questions or comments.
