Subject: [PATCH] Fix disk usage calculation and regex pattern

- Change default disk stats to use root volume "/" instead of summing
  all volumes from /Volumes, which included external drives (fixes #250)
- Fix invalid NSRegularExpression pattern "/ +/g" (JS-style) to use
  Swift's split(separator:) directly
