Bump version

Overview of changes:

 *  Added generic config file finder

    This can be used to find config files other than INIs but using the
    same merging mechanism.  For example, `saturnin__conf_find "foo"`
    should output to first existing instance of file "foo", which could
    live under any of paths set in SATURNIN_CONF_PATH (typically
    /usr/share/app/ini.d/dist/foo, /etc/app/foo, ~/.config/app/foo,
    ~/.config/app/ini.d/my/foo...).

    This function is now also internally usef by saturnin__conf().

 *  Added module-version meta-data for future Shellfu generations

    Current version of Shellfu does not support this yet, but in future
    it should read this and display in lists, man pages, etc.
