Remove featured image support from playlists. May be used again in the future to set playlist artwork or as a fallback.
Minor whitespace tweak.
Update the template loader library to break both foreach loops when a template file has been detected.
Remove extra text domain filters.
Refactor admin code and include player feature.

Encapsulated the admin code in a class.

Players are registered by a theme hooking into the 'cue_players' filter.
Themes still need to build the players and their behavior, but this
feature allows Cue playlists to serve as the source of their tracks.
Fix callbacks for preparing attachments for JS.
Update cue_player() to pass arguments to cue_playlist().

Reduces duplication and provides a fallback in the event a player
template doesn't exist.
Move the main plugin class into a separate file.
Use the playlist featured image as the player background if it's set.
Use the featured image as a fallback URL for the track artwork if it doesn't exist.
Explicitly declare the main plugin variable as global to prevent output on activation in some environments.
Short-circuit cue_playlist() if the post type isn't cue_playlist.
Allow playlist JSON settings to be filtered.
Update the grunt-wp-i18n package.
Update the POT file.
Update the readme changelog.
Bump to version 1.1.0
