Multiple audio track support (#681)

* Support for multiple alternate audio tracks * Separated segment loading logic into a reusable piece of functionality so that we can have more than one segment loader and they can manage the segment fetch behavior unique to each playlist they are loading from * Introduced the MasterPlaylistController to coordinate the loading of the master playlist and separate the behavior of the player from videojs-contrib-hls.js leaving the latter to be the glue between HLS and the video element's events * Added the SourceUpdater to manage the asynchronous bahavior of SourceBuffers and MediaSource objects so that we can treat it as a non-blocking work queue * Added parsing for MediaGroups in master playlists * Added support for AudioTrackList objects and events * Add support for every HLS mime type possible (#684) * Flash live fixes (#682)

+# Multiple Alternative Audio Tracks
+## General
+m3u8 manifests with multiple audio streams will have those streams added to `video.js` in an `AudioTrackList`. The `AudioTrackList` can be accessed using `player.audioTracks()` or `tech.audioTracks()`.
+## Mapping m3u8 metadata to AudioTracks
+The mapping between `AudioTrack` and the parsed m3u8  file is fairly straight forward. The table below shows the mapping
+| m3u8    | AudioTrack |
+|---------|------------|
+| label   | label      |
+| lang    | language   |
+| default | enabled    |
+| ???     | kind       |
+| ???     | id         |
+As you can see m3u8's do not have a property for `AudioTrack.id`, which means that we let `video.js` randomly generate the id for `AudioTrack`s. This will have no real impact on any part of the system as we do not use the `id` anywhere.
+The other property that does not have a mapping in the m3u8 is `AudioTrack.kind`. It was decided that we would set the `kind` to `main` when `default` is set to `true` and in all other cases we set it to `alternative`
+Below is a basic example of a mapping
+m3u8 layout
+``` JavaScript
+{
+	'media-group-1': [{
+		'audio-track-1': {
+			default: true,
+			lang: 'eng'
+		},
+		'audio-track-2': {
+			default: true,
+			lang: 'fr'
+		}
+	}]
+}
+```
+Corresponding AudioTrackList when media-group-1 is used (before any tracks have been changed)
+``` JavaScript
+[{
+	label: 'audio-tracks-1',
+	enabled: true,
+	language: 'eng',
+	kind: 'main',
+	id: 'random'
+}, {
+	label: 'audio-tracks-2',
+	enabled: false,
+	language: 'fr',
+	kind: 'alternative',
+	id: 'random'
+}]
+```
+## Startup (how tracks are added and used)
+> AudioTrack & AudioTrackList live in video.js
+1. `HLS` creates a `MasterPlaylistController` and watches for the `loadedmetadata` event
+1. `HLS` parses the m3u8 using the `MasterPlaylistController`
+1. `MasterPlaylistController` creates a `PlaylistLoader` for the master m3u8
+1. `MasterPlaylistController` creates `PlaylistLoader`s for every audio playlist
+1. `MasterPlaylistController` creates a `SegmentLoader` for the main m3u8
+1. `MasterPlaylistController` creates a `SegmentLoader` for a potential audio playlist
+1. `HLS` sees the `loadedmetadata` and finds the currently selected MediaGroup and all the metadata
+1. `HLS` removes all `AudioTrack`s from the `AudioTrackList`
+1. `HLS` created `AudioTrack`s for the MediaGroup and adds them to the `AudioTrackList`
+1. `HLS` calls `MasterPlaylistController`s `useAudio` with no arguments (causes it to use the currently enabled audio)
+1. `MasterPlaylistController` turns off the current audio `PlaylistLoader` if it is on
+1. `MasterPlaylistController` maps the `label` to the `PlaylistLoader` containing the audio
+1. `MasterPlaylistController` turns on that `PlaylistLoader` and the Corresponding `SegmentLoader` (master or audio only)
+1. `MediaSource`/`mux.js` determine how to mux
+## How tracks are switched
+> AudioTrack & AudioTrackList live in video.js
+1. `HLS` is setup to watch for the `changed` event on the `AudioTrackList`
+1. User selects a new `AudioTrack` from a menu (where only one track can be enabled)
+1. `AudioTrackList` enables the new `Audiotrack` and disables all others
+1. `AudioTrackList` triggers a `changed` event
+1. `HLS` sees the `changed` event and finds the newly enabled `AudioTrack`
+1. `HLS` sends the `label` for the new `AudioTrack` to `MasterPlaylistController`s `useAudio` function
+1. `MasterPlaylistController` turns off the current audio `PlaylistLoader` if it is on
+1. `MasterPlaylistController` maps the `label` to the `PlaylistLoader` containing the audio
+1. `MasterPlaylistController` maps the `label` to the `PlaylistLoader` containing the audio
+1. `MasterPlaylistController` turns on that `PlaylistLoader` and the Corresponding `SegmentLoader` (master or audio only)
+1. `MediaSource`/`mux.js` determine how to mux
