Introducing custom/native/embed skins

Android support

rate won't be supported on Android for a while as the native
MediaPlayer class doesn't support it either.

Remove seek from state.

- Newer syntax.
- Removed lodash dependency.
- Removed hard-coded ref.
- Seek using state.

Bump Example in master to use .10-rc, also fix example to actually go full screen.

Use lodash instead of merge, unbreaking the component (for us)

Absolute positioning of all 0s was with TouchableOpacity using Animated.View, need to also specify that the Animate.View is full screen as well.

Upgraded to .10rc and .60, also added RCTWebSocket to the Xcode project since it wasn't there.

RN 0.10 compatibility: switch to returning an array from customDirectEventTypes
