Fix: removed "get all tasting for a user" since it would have failed sometimes.

Would have failed in the case where a userID and a user wine id were the same.
fix: http_wine_load.py is not so noisy now.
Feature: query parameter extended_listing will expand out references / parents

This parameters causes the resulting JSON to have the parent items added under
their type names and any ID references to be replaces with the item they
reference.
Feature: if cellar_id isn't provided, assume the cellar for the current user.
fix: use rest proxy instead of ajax (mostly for consistency)
Feature: update Inventory / Truth to use new server API.
