Proxy LCD – desktop application

In first part we saw a summary (hardware and software) of remote LCD. Such remote LCD works on NodeMCU and can be accessed via network. It was first stage of bigger project.
Now is time for second part, a desktop application. Its main task is to manage remote LCDs and provide a way to send content from computer to display.
One may add/remove node and set a stream option. What is stream option?
App works in two ways (one for now :P, second option in 3rd phase) if it receive content and it is not a proper packet it iterates over all added lcds and streams data to them. Difference between display and stream is that stream as name says is just a data stream and it send chars one after another. When it reaches end of available space on display it starts over.
In case of packet it will send formatted content to node.
