Fixed bug 2496 - mouse left button double click event issue

cplu

When I double click on a window, the "clicks" field (newly added since 2.0.2) in SDL_MouseButtonEvent is 1 instead of 2.
However, when I "tripple" click, "clicks" field is then 2.
I'v look into the source code in SDL_windowsevents.c and found that when a double click event comes, WIN_WindowProc will get a WM_LBUTTONDBLCLK msg. The message sequence of a double click is:WM_LBUTTONDOWN->WM_LBUTTONUP->WM_LBUTTONDBLCLK->WM_LBUTTONUP.
