REGRESSION: Video control fails to hide after playback begins in reflowable EPUB files

The iBooks app turns off the requirement for a user gesture
before triggering playback. When we moved to script-based
media controls there were a few regressions in this setup.
This makes them behave a lot more like iOS 7.

* Modules/mediacontrols/mediaControlsApple.js:
(Controller.prototype.setPlaying): We don't want to hide the controls
yet, just start a hiding timer.
* Modules/mediacontrols/mediaControlsiOS.js:
(ControllerIOS.prototype.shouldHaveStartPlaybackButton): If we've ever
played before, we don't want to show the big start button. If we
are in the middle of construction, we do want to show it. We no
longer care about the case where you're not in setup and have
the relaxed restrictions (we still want to show the start button
in that case).
(ControllerIOS.prototype.showControls): When we show the controls,
make sure our timeline is up to date. This is necessary for the
cases where we automatically show the controls, such as when we hit
the end of a video.
(ControllerIOS.prototype.updateTime): Make sure to pass the forceUpdate
parameter on to the super-method.
(ControllerIOS.prototype.setPlaying):
(ControllerIOS.prototype.progressFillStyle): Deleted.
