sspitzer%netscape.com b60d6df7c4 fix for #105126. define a default height for the thread pane when using the
normal 3 pane layout.  without a default, the splitter between the thread pane and the
message pane jumps when we switch folders, which looks bad and causes a repaint,
which is bad for folder loading performance.  r=cavin, sr=bienvenu
