winhlp32: Links are clicked on WM_LBUTTONDOWN not WM_LBUTTONUP.

This behaviour was tested against native winhlp32 by pressing down the
left mouse button and holding it while over the link to avoid having
WM_LBUTTONUP sent.  I noticed that the action for clicking the link
happened right away, without waiting for me to release the mouse button.
