Add BuildableStackedSlide.undo

This will be useful if an add method returns false, so that the errant
element can be removed without sabotaging the entire first buffer.
Add SlideEncapsulator

This will be used by my SlideList implemetations to prevent the display
unit from messing around with the Slides. Given that
DefaultEventResultsSlideList currently uses BuildableStackedSlides, this
is pretty important.
BuildableStackedSlide Javadoc: Add blank list of ColorScheme keys
Add DefaultEventResultsSlideList[DERSL].createNewSkeletalSlide

I'll use this whenever I need to generate a new slide.
DERSL: Add evtTitle to ColorScheme key list
Add DERSL.addResType
Make DERSL.addResType boolean

This boolean return signals whether any of the adds failed. False
indicates an overflow.
Add DERSL.addHonorName
Add the transparent color

This will be used for rendering text that is needed for alignment but is
otherwise invalid (ex. when rendering ties, the place number is only
visible on the first row).
Add DERSL.tryAddTie

Unlike the previous methods, this one resets and quits if an attempted
addition fails.
Add DERSL.forceAddTie

This forces the addition, using multiple slides if needed. It also
pushes, unlike tryAddTie, which only commits (it's waiting for the
entire block of results, or entire special honor, to be authored before
pushing). This is because if we're forcing a tie onto the slide, we
already know we want it there without a question, so there's no point in
reverting it.
Add ArrayUtils.multiSort

Intending to use this to sort the honorees involved in ties, while
keeping the schools associated with the corresponding honorees.

Like a good programmer, I'll probably go ahead and write unit tests, but
no guarantee on when that will be.
Clarify ArrayUtils.multiSort behavior in corner cases
Even more additions to Javadoc ArrayUtils.multiSort

This is a complex method!
Make the addTie methods sort the components of the tie

This is the reason for ArrayUtils.multiSort.

As a side note, that ArrayUtils class is becoming very, VERY useful...
