patch 8.1.0472: dosinst command has a few flaws

Problem:    Dosinst command has a few flaws.
Solution:   Register DisplayIcon, DisplayVersion and Publisher for the
            uninstaller. (closes #3485)  Don't set 'diffexpr' if internal diff
            is supported. Allow for using Vi compatible from the command line.
            Remove needless sleeps.  Add comments in the generated _vimrc.
            (Ken Takata, closes #3525)
