Shellfu v0.10.4 - FloatingPointError

Overview of changes:

 *  Revamped version directive format

    This is a backwards-incompatible change, but is an exception because
    (well, we're in 0.x.y phase and) it's only used in manpage
    generator, so at worst people will lose the version info from
    manpage footer.  Also it hasn't been around for a long.

 *  Moved most sfdoc code to separate module

    Yet another module has been born.  This enables better design, reuse
    and also easier testing.

 *  mkusage will not force empty line before indent mode (-i)

    This way it's much more useful; one can produce much more concise
    listings (*and* have them indented, *and* read them from array).

 *  Added -o|--only option to sfdoc for single-directory sets

 *  sfdoc will now correctly report module version (not Shellfu version)

 *  sfpath now supports -V, short version of --version-semver

 *  sfpath now makes sure to sort items consistently under C locale

 *  Added __usage sub-command to shellfu()

 *  Moved perl dependency correctly to shellfu-bash-inigrep

 *  Fixed bad shebang line (thx lintian)

 *  Solved or muted last ShellCheck issues

 *  Revised coding style an docstrings

 *  Codebase maintenance
