title: Qt ignore makefiles, .pro.user files
body: <p>I develop Qt-based project and use Mercurial repository (bitbucket.org service) for version control.</p>
  
  <p>Each time I do commit in repository, there are some files which contains only date-time changes in headers. So each commit I should check each file that it has major changes, not only time stamp.</p>
  
  <p>Could I add makefiles (Makefile, Makefile.Debug, Makefile.Release) and .pro.user file ext. to ignore list? 
  I mean is it possible to regenerate them via launching qmake tool from Qt Creator?</p>
