Implement additional methods from the NSTextInputClient protocol so that more

features of the IME work. attributedSubstringForProposedRange:actualRange: and
characterIndexForPoint: now have full implementations.
This required using UTF-16 document indexes in many places as that is what
Cocoa wants. Tentative undo is used for the composition text instead of turning
off undo as that is safer and similar to IME code on other platforms.
