* issue 310 - Added a new property, ignoreSilentSwitch. When true, audio will play even when the silent switch on an iOS device is set to silent. When false, the audio will toggle with the silent switch. Sets the AVAudioSession to either playback or ambient.

* Added ignoreSilentSwitch usage to example app and to readme

* Changed ignoreSilentSwitch to accept two string values, ignore and obey.
This accounts for the case where the user does not want to modify the audio session from a particular video instance. The user would not use the ignoreSilentSwitch property at all in that case.
Also, the audio session will only be updated when the video is unpaused, instead of whenever the video component has updated props. This allows for multiple videos to be on the screen, with the most recent video unpaused (aka played) being the video that has control over the audio session.

fix(RCTVideo.m): Fixed status bar disappearing issue

This is related to the comment on #368

Before, when you resumed the app the player would **always** start playing again.

After this changed the `paused` prop of the `Video` component (which is the `isPaused` variable internally)
is consulted on resume for whether or not the playback should resume as well.

* added listener for timedMetadata event.

* added callback in RCTVideo for the timed metadata

* exposing onTimedMetadata to JS

* returning array of string values

* added metadata type to the array

Corrected the instructions for running the example

* Fix require(...) file resource on Android production

* Update example (use require for ./broadchurch.mp4)

* Fix MainApplication.java of example

* Add default source type

- Use NSNull object in NSDictionary when type (or URI) missing from supplied
  src object.
- In addition, defensively supply valid strings for URI and type from JS.

The transform matrix was not being recalculated when the View
dimensions changed. Fixed by copying the code from the scaleVideoSize
method from the ScalableVideoView.

When directory structure was refactored, source files were moved to `ios/` dir, but the podspec wasn't updated to reflect this.
