Fallout Styled server/terminal installer

--[[
    To download this to a computer, run this command in the command line:
    pastebin get mrgQrQXB startup.lua

    Once it has downloaded, reboot the computer
    It will prompt you with a choice between this being a terminal or a server

    After you make your choice, type it in, and hit enter.
    This will install the needed files to the computer.

    When it is finished, run the following command:
    edit startup.lua

    Here you can change the settings to whatever you want

    For a server:
        Name: The name of the server. This will be shown to all connected terminals
        Port: The port of the server. This is a unique number for terminals to send commands to
        Side: The side of the block where the modem is located
        Cable: The bundled cable where to output the redstone signals
        GuiColor: The color of the text for the server interface

    For a client:
        Name: The name of this terminal. It will be displayed on the terminal interface and used to identify which terminals are doing what on the server. This helps with debugging to make sure things are working
        Port: The port of the terminal. This is a unique number needed for the terminal to get the response from the server when running commands
        ServerPort: The port of the server. This is needed so the terminal knows where to send it's commands
        Side: The side of the block where the modem is located
        GuiColor: The color of the text for the terminal interface

    After you finish configuring the computer, press the [ctrl] button on your keyboard then [enter] to save the file
    Finally, restart the computer again.

    Now the only change that needs to happen is on the terminals. They will have a file called data.json
    This file contains the logs(texts) and menus that the terminal will show.

    For Texts, each one will need a unique key.
    In the Text object, you will need three parts. An id, title, and txt. Here is an example:
        "key": {
            "id": "key", << This needs to be the same as the one above!
            "title": "The text to display on the UI when selecting a log",
            "txt": "The contents of the log that will be displayed after opening the log"
        }

    For the menus, each one will also need a unique id. Though, you can have the same ID for a menu and a text, it would be best to have them not be
    Here is an example:
        "key": {
            "id": "key",
            "title": "The text to display as a sub-header"
            "cmds":[
                [
                  "toggle 100 1",
                  "Lights",
                  false
                ]
            ]
        }

    For the commands, each will be a button to select on the menu. It is an array
    The first string in a command's array is the command to send to the server
    The second is the text to display on the menu.
    For toggle commands, you can invert the displayed text. This would show that it is on when no redsstone signal is being sent out. This is just for cosmetic purposes and functions the same either way

    These are the current commands that can be sent, more will likely be added:
        "name:{terminalName}" - This sends the terminal's name to the server and the server sends back the server name
        "toggle {targetPort} {color}" - This will toggle the signal of the bundled cable at the server targeted. The color needs to be the numerical value which will be listed below
        "trigger {targetPort} {color}" - This will toggle the signal for the color and then, after a second, toggle it again.
        "check {targetPort} {color}" - This checks if the specified color cable is being output or not
        "stop {targetPort}" - Stops the specified server
        "ping {targetPort}" - Pings the server

    Numeric values for the color for bundled cables
