Multiple AIs can use single holopad

First babysteps coding. This bugged me when I was AI in 3 AI round. Now any number of AIs can use a single holopad. However, they cannot hear each other say things via holopad. I didn't want to dig into say code too much, some advice on that would be appreciated. Do let me know if there's poor code in here.
Don't comment unused things out, just remove them. Code gets pretty messy if there's random old commented out stuff everywhere.
