Merge pull request #1 from ripieces/master

Fixed delegate
Added a game property to determine whether to use the "SteamApps/common" folder, rather than "SteamApps/<account name>".
Added CS:GO support.
Use "common" as the default Steam account name.
Don't pester the user to set Steam preferences on first run - the defaults are probably fine, and there's friendly error messages if they're not.
Removed server browser.
