Lots of changes to .ECS classes

GroupManager is now a Singleton class
Added a window where users can confirm the positions of: ClientOverlay,
ChampionSearchbar, TeamChat
FancyBalloon now matches the colors of our pallette better, still needs
some tweaking
A settings class has been added to control settings easier
wndConfigLolClientOverlay uses 'Thumb's' to let the user choose the
position of the rectangle but aren't working yet, I will be looking to
fix this first
