Updated for 1.191.0

All credit to etopsirhc's Transmitter and Receiver script for inspiration and my starting point
Transmitter and Receiver

I really liked etopsirhc's script but I'm lazy and didn't want to configure settings. :)
This script takes his idea and makes it simpler to use.

The enhancements are:
- The same programmable block can transmit and receive
- No script configuration required
- If you do use configuration, it can be done with CustomData (so it survives script updates)


To receive commands:
- Create a programmable block with this script
- Create timer blocks to perform actions that you want to remotely activate
- Create an active antenna

// This step appears to not be needed with current SE versions
//- Assign this programmable block to the the antenna

To send commands:
- Create a programmable block with this script
- Create an active antenna (make sure broadcast is enabled)
- Call this programmable block with the <name of a timer block> on the _REMOTE_ grid

If you also want to send text messages to display on a remote panel, then it requires a little extra work

To receive text messages, you also need to:
- Name an LCD panel: SimplerTransmitReceive Panel

To send text messages, you call the programmable block with
- text:rest of message here


With that minimal setup, two grids can talk to each other without any other configuration. However, it is possible to set some options using the programmable block custom data (and then click Recompile).

You can also specify the channel for _sending_ with each command, e.g. baseChannel::toggleHangar

That way you can have one programmable block on the sending ship, but target different receivers easily.

To be as cpu friendly as possible, the script does not try to drain the message queue each time it runs. So if you send a lot of message quickly to a single receiver, it is possible to drop messages (game limit of 25 per listener).

Try to keep it to one message per tick for a single receiving antenna and single PB setup.


*** LIMITED SUPPORT ***
I've added limited support for broadcasting the contents of an LCD. Keeping this simple (as per the name) also means there aren't a lot of options.

Sending the programmable block lcd:<lcd name> will cause it to transmit the contents of that lcd.

lcd:channelName::<lcd name> should also work (note the :: between the channel to use and the lcd name)

On the receiving side, if there is a panel with exactly the same name, its contents will be replaced.
If there is no matching panel, then it will not update any panel by default (you can set strictLCDMatching to false)
