I know for a fact this'll be a problem going forward. No idea what else might be.
first pass at implementing connection choosing. Seems to work on Haystack 2; need to downgrade to 1.x and see if anything broke.
fix for 1.x (and 2.x if only one connection [default] exists) when trying to work on multiple connections.
only highlight the current backend if it's in the query string (stops 1.x [and 2.x with only one connection] highlighting)
put version everywhere, for future bump versioning.
fixing packagey bits.
Bump version: 0.4.0 → 0.5.0
