[Tomi Ollila <tomi.ollila@iki.fi>]

Added target `verify-version-news` which checks that the first line
in NEWS file has the following properties:
    First word is 'Notmuch'
    Second "word" matches the current version
    Rest of line is in format (201[2-9]-[01][0-9]-[0-3][0-9]
---

Tested by executing the following commands:
  make verify-version-news
  make verify-version-news VERSION=0.13
  make verify-version-news VERSION=0.12
