Rails3 and Rails4 compatibility

This minor release changes some dependencies to allow the lib to work in rails3 and rails4.

Bug fixes and improvements

Some of the fixes and improvements:

• airplay-cli is now 1.0.0 freezing the API.
• Prevent crash when interacting with a device without extra info (resolution) #49
• Airserver compatibility #35
• Airserver and AppleTV can be distinguish with device.type
• Starts using Reel as the internal webserver
• Fixes bugs on re-connection
• Connections without ip #46
• Adds help to the CLI #52
• Prevents infinite streams #47
• Unit tests until the co-located AppleTV is online
• General stability.

Brand new Airplay!

Airplay had a complete rewrite. Now with a lot of features.
This attempts to maintain compatibility with the latest firmware of the Apple TV.

The API is now simplified as you can see in the README.

Some of the features:

• Custom node aggregation
• Grouping
• Serve local videos
• Video playlists
• Playback control
• Sample CLI

The future is also promising:

• Custom subtitules
• Custom audio tracks
• More device compatibility
• Hidden features control (eg: volume)

This is a major thing for me. A lot of research and suffering is behind this release.
I want to thank some people:
@foca, @pote, @janogonzalez, @soveran, @sodabrew and @CUBEMike

This leap in development is possible thanks to the community... so 1 million internet dollars for them.
