Jonathan Westhues 0246add3e9 Replace ugly text links to hide/show things with icons. So add code 
to draw those, and hit test with the mouse, and display tool tips
when the user hovers with the mouse. Also, underline links only
when they're hovered, and not otherwise.

And add a separate menu option to align the view to the active
workplane, vs. activating the active group's workplane, and
remap the bottom two graphics window toolbar icons to that and
"nearest iso view" instead of draw in 2d/3d, since people tended
to click on those without understanding and cause trouble.

And by default, we force a parallel projection; so the factory
default camera tangent is now 0.3, not 0.
