Better state machine for handling middle mouse button
emulation.
* Clicks shorter than EmulateMidButtonTime are no longer lost.
* The middle button event is generated as soon as both the left and the
right buttons are pressed. The old code waited until the timeout had
passed before even checking if both buttons were pressed.
