[SDL] Detecting Double Clicks

[Fro Joe]

Okay.  I said we'd do this like Borland did in the VCL, which I'm sure most
people probably haven't used, but I did explain it.

There would still be a mouse down and mouse up event that would be generated
the instant the mouse button went down or up.  A click or double-click event
would be generated later.  This would be useful specifically for point and
click games (like a RTS... like Starcraft).  Basically, it would end up as a
totally new event type.
