Fixed hub to repsect win-interactive class when handling key inputs. Fixes #722
Add slight border to select per design feedback
More changes based on feedback on select styling.
The redlines were mostly already updated, but there was a bug in them that broke our MSDN sample by assuming that win-header should appear inside of the win-content element, but all of our samples don't do that.
I also updated the a few redlines changes to the win-header.
Fixed a positioning issue with the prev nav button.
Update NavBar styles to match new redlines

color-definitions.less was updated. @colorMid and @colorMediumMid are
currently the same and that's okay. We want to keep them both in case we
want to change them to different values in the future.

Also updated some NavBar tests:
- VerticalKeyboarding: Had to be updated due to changes in the heights of
  the viewport and commands
- DataEdits, ArrowKeysPressed: Made these tests faster (they were quite
  slow in Firefox)
Flyouts and Menus now take focus synchronously after firing their "beforeshow" event, instead of blocking on animations first.

     Add CSS styles for activated 'flyout' typed MenuCommands to indicate which command in a parent menu links to the current subMenu  (in cascading Menu scenarios)
     Added logic to bind the activated state of the MenuCommand to the shown state of the sub Menu/Flyout
     Add Unit tests.
Fixing lint error.
Renamed AutoFocus src files to DirectionalFocus.
Renamed references to AutoFocus in src to DirectionalFocus
Fix input field styling. Closes #725.
Remove legacy documentation file.
Fixed unit tests that are broken in Win10 due to changes in MSManipulation
event. Fixes #631.
Further updates to selection visuals from design. win-selectionstylefilled + tapBehavior=toggleSelect + selectionMode=multi will now enable the 'selection mode' visuals in all layouts (previously it was only applied to vertical list).
Fixed a race condition in Hub tests that caused tests to fail on slow
machines. Fixes #611.
