wic: Rename /mic to /wic

As well as any other stray instances of mic in the codebase that can
be removed.

We don't really need to carry around legacy naming, and the history is
in git.

-"""An improvement on Python's standard cmd.py module.
-
-As with cmd.py, this module provides "a simple framework for writing
-line-oriented command intepreters."  This module provides a 'RawCmdln'
-class that fixes some design flaws in cmd.Cmd, making it more scalable
-and nicer to use for good 'cvs'- or 'svn'-style command line interfaces
-or simple shells.  And it provides a 'Cmdln' class that add
-optparse-based option processing. Basically you use it like this:
-
-    import cmdln
-
-    class MySVN(cmdln.Cmdln):
-        name = "svn"
-
-        @cmdln.alias('stat', 'st')
-        @cmdln.option('-v', '--verbose', action='store_true'
-                      help='print verbose information')
-        def do_status(self, subcmd, opts, *paths):
-            print "handle 'svn status' command"
-
-        #...
-
-    if __name__ == "__main__":
-        shell = MySVN()
-        retval = shell.main()
-        sys.exit(retval)
-
-See the README.txt or <http://trentm.com/projects/cmdln/> for more
-details.
