Trying to add SwiftyJSON.

There is an error when compiling the tests which I must sort out:
/Users/danielbevenius/Library/Developer/Xcode/DerivedData/
AeroGearSyncClient-gxrfxmdnqqgazsgrtmxvktnvhkpt/Build/Products/
Debug-iphonesimulator/AeroGearSyncClient.framework/Headers/
AeroGearSyncClient-Swift.h:67:9:
error: include of non-modular header inside framework module
'AeroGearSyncClient'

Reverting to using submodules.
Replacing SocketRocket with starscream.

At the moment I'm currently using my own fork of starscream. Hopefully
this is only temporary[1] until there is support for specifying the
protocol for the WebSocket protocol negotiation.
