Fix a Unity annoyance with mouse cursor and play mode button.

OMGMoveTheCursorOnPlayMode.cs

/*
This fixes an issue you'd encounter if...

1. You hit the play button with the mouse cursor.
2. You lock/hide the mouse cursor.
3. You click a mouse button (presumably right or middle mouse) to show the mouse cursor again.

In this case, you will find that the mouse cursor is still on the play button, and the click which unhides the cursor 
will press the play button, thus stopping the editor. This happened to me most often when I would use a gamepad after
hitting play, but would want to edit something via the mouse. Not a common issue, but once you accidentally stop your
game several times, a fix becomes desirable.
