Clean up some selection operations. Commonly when changing selection modes,

all of the selection needs to be redrawn so that is implmeneted in
Editor::InvalidateWholeSelection. Any extra selections should be discarded with
only the main remaining so that is Selection::DropAdditionalRanges.
Some default parameters led to less clarity so they no longer have default
values. Both Editor::MovePositionTo methods always returned 0 which was ignored
so they are now void. Some variables were made const.
