[Gameplay] Moving while chat box is open!

This was quite the painful bug to figure out, but this bug happens on every map. Basically when ever I would have my text box open in game and type a message occasionally my character would move to where ever my mouse is located on the screen!

I've traced the error back to this case...

1. Change your default pet movement to any single key. (Example. For the shaco ult: I wanted to hit 'T' to move my clone, since alt is really awkward on a mac)
2. Whatever this key is, when you have your chat active clicking that key while typing will cause your character to move to your current mouse location. (Example. Typing "wai(t) to engage!" could cause me to run into the enemy team if my mouse is in the wrong spot.)
