Bump version

Overview of changes:

 *  Added 'newstub', builder script to help with new projects

    The script is intended to help start up new MKit project by generating
    structure necessary for MKit to work, and instructing user which
    parts to review and how.

 *  Fixed bug when skeletons could be deployed as part of directory

    If directory targeted in [files] section contained .skel files, they
    would get deployed along with built files.

 *  Code refactoring

    Moved global variables to new vars.sh module, improved initialization
    and importing code and added file headers.

 *  Improved patch importer utility
