Improves commit message scripts

From: Mauro Carvalho Chehab <mchehab@infradead.org>

This patch improves message description sanity rules:

- mailimport now prefers to edit using editdiff. This helps to fix
  trivial CodingStyle errors at receive patches;

- hghead.pl will now remove blank whitespaces if no body exists;

- "make commit" will now run hghead.pl. This will do some sanity checks
  at commit messages:
  *) Will warrant that "from:" metatag exists, avoiding to have patches without
     proper authorship id at someone's else tree;

  *) Will order the tags at the expected way (subject, from, body, signatures);

  *) Will warrant that one and just one blank line exists between each of the four
     parts of the commit message.
