Database store for EDDN

In an attempt to bridge the gap between where EDDN is now, and systems like trade dangerous, I've implemented my first go at storing and publishing data from EDDN. If it gets enough interest, I'll add more features. Let's see what response this gets.

You can get a trade dangerous-ish dump of my database from - It's real-time (IE, calling this URL reads the data from the database, not a pregenerated file). The database is updating from EDDN in real time.
