Bump version

Overview of changes:

 *  Fixed issue that would break release

    Releases with many commits or many changed files can produce 'Bump
    version' message so long that it would trigger OS command line limit.
    This risk has been mitigated by ensuring the message is read from
    file instead of git argument.

 *  Added "SRC" mode to preserve file modes from repository

    Sometimes the mode scheme is not easy, so having mode to apply to
    whole group is not plausible.  Setting group mode to a special value
    `SRC` will cause MKit replicate the mode from source (repo or
    tarball).

 *  `stub new` will produce "nice" mkit.ini right away

    Previously, re-formatting of mkit.ini would work only in update
    mode; now it's nicely re-formatted on creation.

 *  Fixed formatting of INI files

    If value in INI file contained space, formatting would break it up.
    This is no longer the case.

 *  Cleaned up specfile template stub

    New specfile template now does not contain tabs, has fields grouped
    in more logical way, and omits BuildRequires, which was not all that
    correct anyway.

 *  Improved README.md
