1) This only creates one softkey menu. If we create more then one, this cause

windows to be hidden between new window creations.  See bug 314552.

2) This also makes a improvement to mouse taps in a context menu.  Now we only
test for tab-and-hold (a "Gesture") when we are not displaying a context menu.
If we don't do this, the check for the gesture makes the context menu go away.

3) We also hide the software input panel when we are creating a dialog or a
window.  This insures that the windows ce SIP button never blocks the view of a
XUL implemented SIP.
