Add CS:GO to Source Service Option (pterodactyl#538)

* Added CS:GO

This allows users to select rather or not to use cs:go for a server.

* Removed debugging outputs

* Replace tabs with spaces to pass StyleCI

* Remove more pesky tabs

I apparently missed them the first time.

* Fix pesky issues with starts

This fix is to repair the startup for csgo and remove the required accounts.

* Better explanation for STEAM_ACC

* Removed dupe ips

* Added and fixed lines

* Set a default map to be loaded in.
* Set the variables rules to match what they would need to be
* Removed a pesky space
