Bump version

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
