Subject: From: Chris Yeoh <cyeoh@au1.ibm.com>

The attached patch implements llPassTouches. It has been added
to the export/import XML along with the flag for AllowedInventoryDrop.

The MySQL backend has been updated as well, though I haven't
done one of those before so could do with a check. I added
the migration mysql file as well.

The other data backends need updating as well.
