Sam Atkins 85101c6626 HackStudio: Keep the DeclarationsModel around, and use a filtering proxy
Rather than construct a new DeclarationsModel each time the user types
something in the Locator, keep a single one around permanently in the
ProjectDeclarations, and then use a FilteringProxyModel over it for the
suggestions.
