Bump version

Overview of changes:

 *  Improved and updated README.md

    Actually, the main reason for this update is to make new README
    visible sooner, since it's been significantly improved.  Most
    important change is that the introduction has been moved to own
    document.  Also Installation section has been clarified.  That and
    some tiny fixes.

 *  Made minor visual improvement to mkusage()

 *  Added tests for mkusage() '-w' option

 *  Made SHELLFU_IMPORTED into an internal variable

 *  Added some ShellCheck exceptions
