LRUCache changes:

Collections-ul.618 patched for Spur by SpurBootstrapMonticelloPackagePatcher Cog-eem.260

Various OrderedCollection changes.

Adding:
- #addAllFirst: can accept any collection as argument, but uses #reverseDo: if the argument has that method. It's implemented with double dispatch by #addAllFirstTo:.
- Simplified and recategorized #at:ifAbsentPut:, but kept the unusual semantics of nil values.
- Simplified #addAllLast: a bit, and updated its comment.

Removing:
- #removeAllSuchThat: stores the read element in a temporary
- #removeFirst: and #removeLast: doesn't use #removeFirst and #removeLast anymore.

Error handling:
- removed the unsent #errorConditionNotSatisfied method
- changed #errorNoSuchElement to use the name of the receiver instead of "an ordered collection"
- added #errorNotEnoughElements, which is used by #removeFirst: and #removeLast:

Other:
- implemented #indexOf:startingAt:ifAbsent: for better performance
- fixed the comment of #isSortedBy:between:and:

- Don't color the background of filtered lists ink because we now have the new improved (yellow) filter-indication.
- Enhancements to the Smart Splitters algorithm:
	- Faster.  Sibling splitters now optimize simultaneously as a group, allowing them to sprint to the balanced position quickly.  This fixes the undesirable creeping behavior.
	- TextMorphs now request splitters to balance their number of visible lines which need to wrap against the opposing widgets occluded characters.
