Bump version

Overview of changes:

 *  Rewrote *newstub* as *stub* meta-command, now with update mode

    The script looks promising, let's use the extensible CLI scheme.

 *  Removed sorting from `ini lskeys`

    *stub* can rewrite user's mkit.ini but it does not want to mess it
    up more than is necessary.

 *  User can now override project version with *stub*

 *  *stub* now Respects MKIT_INI environment variable

 *  Fixed problems with LICENSE.md and README.md rewriting in *stub*

 *  Moved MKit version directive to end of file

 *  Improved MKit's own project README.md
