    Makes Impact bug creation generic, ceases doc spam
    
    This patch moves the bug creation code to its own method, so that it
    can be used by other kinds of impacts.
    
    It also changes the notification logic for DocImpact, so that emails
    are now only sent if bug creation was not successful.
    
    This patch should have no effect on other kinds of impacts.
    
    patchset3 fixes use of sys and updated docstring
    
    patchset4 rebases to master
