[Dyl0n]

I changed this up a bit.. I don't know how to do much but I got it to work and compile with no errors.

It will log with the persons name + steam id + the command they used + the args they used for that command if any.

Logs to tf/logs/execcommands.log (I created a log folder there.. idk if you will have to)

Again, I don't know much about coding this kind of stuff and mostly go off of examples so I'm sorry if anything is wrong.
