Just pushed lacinia-pedestal 0.5.0-rc-1 to clojars

Comments are welcome; once we have lacinia and lacinia-pedestal running in our production servers, we'll do the formal releases.

... and I've found a problem where Pedestal 0.5.3 adds Content-Security-Policy headers by default that cripple GraphiQL. rc-2 coming up ...

Expectation: We're in holiday lockdown, so the final (non-RC) releases will happen after Black Friday. I've also just pushed lacinia-pedestal 0.5.0-rc-2 to clojars.
