Fix various issues with http inventory

1) The return messages were being wrongly populated with the names of asset, inventory and sale types when their corresponding integers should have been used instead.
2) Folders with links were including the linked items in the descendents figure, when only the links should be included.
3) Links and linked items in link folders were not being included in the return data, and not in the correct order.

Now that these issues have been addressed, outfits and attachments appear to work consistently when HTTP inventory is enabled (as is now the default).
