Major backport of 8.6 Ttk for 8.5.9. Most changes were only being

        committed to head (8.6), although they could apply for 8.5 as well.
        This re-sync makes future work easier to maintain and adds some
        useful work for 8.5 users. Notable changes:
        - Lots of code cleanup
        - Some bug fixes never backported
        - Addition of ttk::spinbox
        - minor color changes
        - Improved Vista/7 styling
        - Move to tile version 0.8.6 (pseudo-package)
        - ABI and API compatible (even $w identify)
        - minor new features (extended $w identify)
