Disable automatic team balance and fix disabling auto-scramble

[kraigher]

I want to use your retake server to practice within my CS-team and we would like to choose our CT/T teams manually and not have the server switch people automatically.

I am a C#-developer so I could make PR for such a feature if you are interested instead of me making a private fork.

Proposal

• [x] Add a AutoTeamBalance configuration option (default=True) that you can use to disable TeamBalance()
• [ ] Also it seems there is some kind of TeamBalance running in CounterTerroristRoundWin https://github.com/B3none/cs2-retakes/blob/master/RetakesPlugin/Modules/Managers/GameManager.cs#L140. This should also be disabled by AutoTeamBalance.
• [x] Fix IsScrambleEnabled. When reading the code I see that IsScrambleEnabled will not disable all calls to ScrambleTeams https://github.com/B3none/cs2-retakes/blob/master/RetakesPlugin/Modules/Managers/GameManager.cs#L79
