Optimize old code (find, kill, write)

[khalidahmedshalabi]

When I had thought of making a clean & proper gamemode for TDM/AAD, I couldn't be bothered and didn't have time to write it from ZERO. So I used Attack-Defend GM as a base script and started to find issues and re-write stuff. After time, I realized how stupid I were by doing this because I ended up re-writing almost everything. Having said all that, there are still some shitty code remaining from Attack-Defend GM code. Our mission is to find it, kill it and write our efficient alternate.
