Bump version

Overview of changes:

 *  Fixed version directive lookup

    mkit.ini would be refused if version directive was at the end of the
    file, while first and last 3 lines is what was supposed to work.

 *  Fixed license argument check

    stub script would ignore license argument due to argument validation
    error caused by refactoring.

 *  Fixed bad grep advice in MKIT_STUB_README.md

 *  Updated own dogfood
