'newstub' was not so far to being able to update meta-data based on
existing mkit.ini.  However, in order to keep the CLI sane, it seems
better to switch to meta-command scheme.

Not everyone likes v0.0.0.  While it's trivial to change, the other
reason for this is scenario when user just updates (re-builds) the
meta-data.

Not everyone wants mkit.ini in the root.

Being consistent leads to much more readable code.
