[PATCH] SubmittingPathces: remove Cogito reference

[Sverre Rabbelier <srabbelier@gmail.com>]

Removing Cogito leaves just git and StGit, which is a rather
incomplete list of git diff tools available. Sidestep the problem
of deciding what tools to mention by not mentioning any.

  I noticed the Cogito reference was never removed. In the light of
  the recent discussion about removing Cogito from the GitSurvey I
  figured now might be a good time to remove this reference as well.
