Bump version
    
    Overview of changes:
    
     *  Split to core+module package
    
        The package now demonstrates a slightly more complex (but more
        useful) distribution model, when part of functionality is also
        exposed as public API via Shellfu/Bash module.
    
     *  Fixed PRETTY_DEBUG_EXCLUDE not being applied
    
     *  Improved and fixed packaging meta-data
    
     *  Codebase maintenance
