fix parallel builds
Created by: iameli
The first change adds an unconditionally copy of the Mist headers to the necessary directory, simplifying a lot of .headers
logic.
The second change adds MistController
as a dependency of MistOutHTTP
so that player.js.h
and other dependencies get generated at the right time. I tried using MistAnalyserFLV
instead, per conversation, but that didn't work.
