Searching for factions, stations, and systems should allow partial completes

[vanderaj]

The backend should be able to return faction names like "The Hive" when "Hive" is typed. Many factions have unique bits like "Ida" which are going to be relatively unique.

I'd prefer to do this without using a meta-character, but it might be useful to gauge performance before turning the queries into "like" style operations permanently.
