Game systems to deal with smurf/ alt accounts

These changes shouldmainly apply to competitive.

1. most basic system this game needs placement matches. Matches must be played solo so people can't boost their terrible friends who don't know how to play the game into higher Elo.

2. Hardware addresses linked to player accounts. The game should only queue lobbies with smurf accounts with other smurf accounts cause people can easily switch to their main and just steam roll the game.

3. Seperate solo queue from teamed queue. Too many matches if you get a horrible duo either one person doesn't know how to play the game or no one is willing to switch because it's their alt account for practicing one hero.
