Check viewer 2/3 attachment calls against avatar appearance attachment data rather than actually attached objects

By checking against the grid's Avatar data, we can ignore viewer side attachments but still initiate these calls simulator-side.
Initiating simulator-side is always necessary for version 1 viewers.
This is a further commit to resolve http://opensimulator.org/mantis/view.php?id=6581
