FramingLayout bug

There seems to be a problem when using a FramingLayout and an
arrangement aspect of #centerRelativeParentHeight.  The culprit seems to
be FramingCalculation class>>centerRelativeParentHeight, which calls
FramingContext>>height, which doesn't exist.  I defined the latter
method (see below) and now it works.

!FramingContext methodsFor!

height
        ^rectangle height! !
!FramingContext categoriesFor: #height!accessing!public! !

oops, you can ignore the attachment in the previous post.  Geez, I'm
getting (have gotten) sloppy.
