--------FUNCTIONS DESCRIPTION--------
01. click right mouse button     -> unselect all cards (same as origin)
02. hold right mouse button      -> multiply select cards (core function!)
03. click middle mouse button    -> esc
04. hold middle mouse button     -> quickly restart (same as key "r")
05. middle mouse up              -> play cards
06. middle mouse down            -> discard cards
07. click X1 mouse button        -> sort hand by suit
08. click X2 mouse button        -> sort hand by value
09. hold gamepad b button        -> same as hold right mouse button
10. click gamepad left shoulder  -> same as click X1 mouse button
11. click gamepad right shoulder -> same as click X2 mouse button
12. hold gamepad right stick     -> same as hold middle mouse button
