rtmp-services: Update Facebook recommended settings

Adds support for 1080p streams, adds support for 60 FPS streams,
implements bitrate matrix to restrict bitrates depending on the user's
resolution and framerate combination, and removes 480x360, as it was the
incorrect resolution (the correct resolution was supposed to be
640x360).
