Wired in options, at least getting as far as the Objective-C bridge. Then fast loading makes it to the emulated machine, display output type doesn't.

Re-enabled working video output for the Electron for the day and consolidated the rough metric I'm using to pick a number of taps for the audio filter.

Attempted to simplify threading, thereby allowing machines to be constructed within a valid GL context, and started adding appropriate GL syncs. Which all oddly drops everything to a negligible FPS. Investigation will follow.

Renamed CSCathodeRayView to CSOpenGLView as it no longer has any CRT-related responsibilities. It just does the GL and manages a serial dispatch queue.
