*  Fixed bug that prevernted saturnin_conf queries to contain spaces

Overview of changes:

 *  Don't hide short options from usage message and Bash autocomplete
 *  saturnin-conf now has usage message
 *  saturnin-conf now exits with useful status in some scenarios
 *  Hacked completion code together so that updating should be easier
    (command name is set only once)

 *  Cleanup and maintenance

Overview of changes:

 *  Improved help and usage messages

    Small but long wished for change; this may improve ability to
    explore apps easily.

 *  Code clean up and maintenance

Overview of changes:

 *  Updated for shellfu 0.9.x

    New shellfu version brings about a lot of changes; this release is
    mostly about catching up with it.

 *  Use predictable meta binary name

    Applications will have updating easier if they use simple generic name
    for meta-command source file; we should set an example (that's the
    point of satcmd, after all).

 *  Minor clean up

Overview of changes:

 *  Maintenance release

It's easier to maintain "state of the art" templates by comparing with
peer projects.

Overview of changes:

 *  Added "last git hash" to application version meta-data (--saturnin-get-*)
 *  Improve meta command template
 *  Build system maintenance

Overview of changes:

 *  Changed default cache path to under .cache subdir
 *  Added --saturnin-get-* for printing Saturnin internal info
 *  Simplified test suite a bit with new TFKit
 *  Enabled Debian packaging
 *  Repo maintenance and cleanup

Overview of changes:

 *  Heavily simplify template maintenance
 *  Update MKit to version v0.0.9
 *  Update MKit packaging meta-data
 *  Add packaging for demo kit
 *  Fix and improve demo kit
 *  Lot of refactoring
 *  Improve docs

Useful for testing saturnin itself

Use of app name when naming of global variables and/or mkit tokens makes
upgrade of the saturnin template painful and error-prone, while none of
these variables can be overriden from environment so the namespacing
advantage is vain.

Since saturnin's dedication to be "meta-command" builder, the distinction
between "meta" and something else does not make much sense.

The routines are all basically related to the meta-command functions.

New command allows to define flexible menus in INI files.

Single INI root now contains all menu definitons.  Each menu consists of
item generator, selector and consumer, which are checked and chained
together.

Alternatively to specifying a generator, items can be listed right in
the INI section.

This module is intended to be moved around with saturnin, but unlike
main meta-command (bin/saturnin.skel), it should not be necessary to
rename it or edit to adapt to new project.
