Demo Messages

I quite often make demos of particular things, tricks, strategies etc to send to my clanmates and I got sick of stopping to type something in to explain what was going on so I wrote this script. It's very simple. There is a list of messages, the last of which is empty ie "". Each time you press the zoom key, it "says" the message, cycling through all of them until it gets to the empty one, at which point it rebinds the zoom key to zoom again. The doNothing() function was necessary because I was getting errors when I released the key, wierd but it is probably fine using later versions of Tribes. I've found that I needed alot of practise run throughs of whatever it was I was demoing, to get the timing of the messages correct with the action.
