src/dict/dictionary: modify term sorting algorithm

Modify term sorting to priorize first terms that have a longer close
body. Terms with longer cloze bodies have matched more text and may
represent a more accruate match in most cases. Next check for expression
size if the close is the same. This prioritizes expressions like
すみません which may have its own definition, but also deconjugations to
another valid term. Then deconjugations with more steps are priortized
as they may reperesent more accruate terms. Finally score is used if all
else fails.
