	const val PUBLIC_SERVER_URL = "https://public.vulnerablecode.io/api/"

API v2 seems to be stable by now. It is also what https://public.vulnerablecode.io/api/docs/ uses.

Maybe this is a good opportunity to give https://github.com/hfhbd/kfx with https://public.vulnerablecode.io/api/schema/ a try.

@pombredanne just disclosed to me that in 3-6 months there'll probably be a v3 of the API. So while current v2 is supposed to be much faster than v1, it's probably worth waiting for v3, as running the advisor is not currently a bottleneck in the compliance pipeline.
