Add "Show in OS" context menu item to open a folder in Finder/Explorer.

Init commit
Small code cleanup
Adds option for strongly preferred prefix and single segment search.

These options make stringMatch produce useful and predictable results in cases that are not
quite the same as file searching (such as code hinting).
Turn on preferPrefixMatches for JS code hints.

Adding this option to string matching provides a fix for #3534 by putting
the matches at the same score and using the scope as a tie breaker.
Extract function to create prefix search result.
