Rename BridgeComponent APIs

[jayohms]

This adds clarity to the BridgeComponent APIs. Components don't merely send messages: they receive messages from the web and reply to those messages (optionally with new event/data).

class TestComponent : BridgeComponent {
    override fun onReceive(message: Message) {
        // handle message
    }

    fun handleSomeUserAction(message) {
        replyWith(message.replacing(jsonData = myNewData))
    }
}

This also marks the Message constructor as internal so apps cannot create new instances themselves. They must reply to existing messages using the .replacing(event, data) method to modify the properties when replying back to the web.
