Updated code for repeat delay / repeat handling. GetKeyPressedAmount() now returns a count to support fast repeat rate (where DeltaTime > RepeatRate). ...

Renamed from recently added IsKeyPressed() variant to GetKeyPressedAmount(). (no API breakage, added in branch, bbd3b75) (#323)

Added IsAnyWindowFocused(). Renamed IsMouseHoveringAnyWindow() -> IsAnyWindowHovered(), IsPosHoveringAnyWindow() -> IsAnyWindowHoveredAtPos(), IsMouseHoveringWindow() -> IsWindowHoveredRect() for consistency. Kept inline rediection function.
