Remove foreach command

We're beginning a transition away from workspaces,
foreach in particular is possibly one of the least used commands,
and is only mentioned in tutorials explicitly marked as 'old'.

-        Use -- before specifying the command to separate its arguments from
-        Morph's own arguments.
-
-        Command line arguments:
-
-        * `--` indicates the end of option processing for Morph.
-        * `COMMAND` is a command to run.
-        * `ARGS` is a list of arguments or options to be passed onto
-          `COMMAND`.
-
-        This runs the given `COMMAND` in each git repository belonging
-        to the current system branch that exists locally in the current
-        workspace.  This can be a handy way to do the same thing in all
-        the local git repositories.
-
-        For example:
-
-            morph foreach -- git push
-
-        The above command would push any committed changes in each
-        repository to the git server.
