Table captions are implemented as children of the table but have a special
requirement to expand to the full width of the table rather than just the 'available'
width, i.e. the full width minus padding and borders.

To accomodate this create a RenderTableCaption object that reimplements containingBlockLogicalWidthForContent()
to return the full width of the containing block (i.e. the table) rather than the available width.

LayoutTests:

Table captions now use the width of the table rather than the width of the table minus
the borders. This allows captions to center accurately but unfortunately a lot of mozilla
table tests need to be rebaselined as many of them use captions for explaining the purpose
of individual test files!

Add border-collapse-offset-002.htm which now renders correctly.
