Overview of changes:

 *  Cleaned up SPEC file template

 *  Fixed bad usage of usage message generator

 *  Fixed a minor typo

 *  Updated MKit and TFKit

As Fedora Package Guidelines say:

    https://fedoraproject.org/wiki/Packaging:Guidelines#.25global_preferred_over_.25define

(Irony not intended...)

Error message was passed as usage pattern, ie. calling invalid subcommand
such as:

    mytool nonesuch

would result in usage message like:

    usage:
      mytool invalid sub-command: nonesuch
      mytool [options] COMMAND [ARG...]

    [...]

Overview of changes:

 *  Made packaging and meta-data updates and improvements

    Mostly refactoring to make better use of MKit's features and provide
    more robust, simpler and maintainable package meta-data.

 *  Fixed typo in first name

 *  Fixed test log header

 *  Added SATURNIN_SUBCOMMAND definition and docstring

 *  Updated MKit to v0.0.28

To make it a bit easier to maintain multiple Shellfu/Bash libraries, we
want to have sort of "template" and keep every module as close to it as
practical.

TFKit will not see it otherwise.

Mostly for purpose of documentation.

Overview of changes:

 *  Added BASH_VERSION and SATURNIN_APP_VERSION to debug output

    Dodge PRETTY_DEBUG_EXCLUDE and report these even in "normal" debug
    mode.

 *  Added upper Shellfu dependency version limit

 *  Changed to shorter name of debian/install file

    The 'package.install' form is for cases with multiple binary
    packages.

 *  Removed extra version parts from (Build)Requires

 *  Updated format of version declaration

    Newer Shellfu changes this format, although dependency changes are
    not justified as almost nothing uses the version directive.

 *  Codebase maintenance

No need to use package name if there is only single binary package.

Shellfu v0.10.4+ will use the newer format.  This does not justify
hard dependency change, as no known functional components rely on the
version; only thing that uses it is sfdoc to display module version in
man page footer.

Overview of changes:

 *  Reverted pre-pending behavior of saturnin__conf_mkpath()

    Turns out it caused more harm than good;  see related commit for
    details.

Turns out this was not a good idea as it would too easy to trigger.
If a saturnin sub-command was called from within itself (or another other
sub-command), the $SATURNIN_CONF_PATH computed earlier would just double,
leading to unwanted behavior of saturnin__conf_find(), which would find
items twice.

The original problem should be adressed another way; the testing case
be covered by either writing tests on a lower level; eg. unit tests
and use saturnin__conf_find() or saturnin__conf() without forking.

Another solution on part of Saturnin could be to introduce different
variable (e.g. SATURNIN_CONF_DIRS) for values computed by launcher
and keep $SATURNIN_CONF_PATH just for user.

Overview of changes:

 *  Made saturnin__mkpath() respect $SATURNIN_CONF_PATH

    Ignoring the environment variable would make it hard to do system
    tests in staged environments (such as RPM's `%check`) that would
    rely on saturnin__conf().

This allows prepending config locations to Saturnin.  This should be
normally used only in cases of staged installattions, such as in sanity
tests.

Overview of changes:

 *  Added --saturnin-get-subcommands devel key

    In last update I inanely removed _ls_sc sub-command used by
    completion example in saturnin-demo.  This is a final replacement,
    which is actually consistent with the rest of plumbing commands.

 *  Improved docstrings for sfdoc

    Added and fixed some old docstrings as well as added module
    docstring.

 *  Improved usage errors with newer Shellfu's pretty.sh interface

    pretty.sh in newer Shellfu can handle usage messages in more
    user-friendly way, by providing option to append error reason
    to the message itself.

    (With previous version, one could achieve similar effect but with
    more negative effect on readability.)

 *  Fixed build-time test for Debian

    Turns out that dehbelper does not install the package on its own so
    we have to deal with it manually.

 *  Minor code cleanup

A less intrusive replacement for _ls_sc subcommand

Overview of changes:

 *  Fixed many packaging errors

    Added proper (build) dependencies, fixed build-time tests (rpm and
    deb), updated meta-data.

 *  Updated code to work with for Shellfu v0.10.0

 *  Removed obsolete internal subcommands

 *  Added support for -V for version (SemVer-formatted)

 *  Changed license to LGPLv2

Overview of changes:

 *  Added option to enable stronger debugging

    You can use PRETTY_DEBUG_EXCLUDE to mute some output from your apps
    that might not be always relevant (example launcher in saturnin-demo
    does this).  This option re-sets the variable to empty string, making
    sure your pretty apps will show as much as possible.

 *  Added tests to deb and rpm packages

 *  Added test header (requires Shellfu v0.9.7+)

 *  Fixed, tidied up and updated project and packaging meta-data

 *  Fixed usage test

 *  Codebase maintenance

$0 is not changed by functions so this could not have worked (strange it
*did* work on Fedora, I still have to find out why).
