sammccall created this revision.
This scale is much easier to mix with other signals, such as fuzzy match
strength.
Mostly NFC, but it does reorder some low-priority items that get folded
together at a score of 0 (see completion-qualifiers.test).
Removed the exact sortText from the testcases, because it's the ranking that we
want to test.
