Added new AVM node type DeletedNode (aka, ghost, tombstone), a marker node for a

node that has been deleted in a version. This makes tree comparisons easier by
resolving the cases in which one wants to know whether a deletions is more or less 
recent than another version of a node.  Along the way got rid of DeletedChild and 
friends including a table in the schema, since DeletedNode takes on all the work
that it performed.
Deleted two illegally named files in Virgin content.
