yowsup-cli demos

• Send read receipts for received messages in cli demo, thanks to @jlguardi
• Fixed Warning that demos are not using YowParallelLayer, thanks to @joaoricardo000

Mostly core updates, and most importantly is the ability for a layer to expose an Interface for direct interaction from other layers/places. For example, doing a yowNetworkLayerInterface.connect() makes more sense than broadcasting an event across all other irrelevant layers. Or a storage layer that saves incoming and outgoing messages, and then a GUI which would like to query a conversation history would request the storage layer's interface which should expose methods like "getMessages"

Protocol

• Support sending receipt for multiple messages

Core

• Layers can now expose an InterfaceLayer for outside interaction
