v1.5.0: 1.5.0 release

- Say line number of match.
  The line number of the selector in mort will now
  be displayed when verbose (-v) mode is set.
  i.e.
      mort -f test/something.css -v
  outputs:
      0 usages found .my-selector:23 (5 lines)

- Print "Done!" when finished, this gives better
  feedback for users using mort through stdin.
- Improve the count of lines a selector occupies
