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)
