Bump version

Overview of changes:

 *  Removed SHELLFU_PATH from default setup

    People are encouraged to put Shellfu modules to standard paths
    anyway (where they can be seen by sfdoc), so this is not very
    useful.  We better get rid of it, taking another (path-related,
    ie. unreliable) token out of mkit.ini.  There's always option
    of modifying app.skel or re-setting the path dynamically (from
    sub-command or by a wrapper), if someone is so ashamed of their module
    (but don't be!).

 *  Hardcoded default name of help file

    Removes the one token that was missing in mkit.ini anyway, causing
    false ugly errors to be thrown at real users.  Again, if people can't
    really use that name, they can alwas modify (or wrap) app.skel.

 *  app.skel now respects SATURNIN_CONF_PATH from environment.

    Ie. tests should work even with v0.4.9+

 *  Moved app.skel right under src

    There's virtually never anything else there.

 *  Added example meta help file

 *  Simplified and cleaned up mkit.ini

 *  Removed unnecessary override in %check

 *  Updated MKit to v0.0.25
