Brief update on UIEvent key testing

I just made an update to some of our key event testing files:

   - I updated the Key Event Viewer
   <https://cdn.rawgit.com/w3c/uievents/gh-pages/tools/key-event-viewer.html>.
   Renamed from Key Event Tester since it wasn't testing anything. Also made
   updates to how the fields are presented and added a sequence id.


   - I also added some manual keyboard tests for 101en-us
   <https://cdn.rawgit.com/w3c/uievents/gh-pages/tests/key-mtest-101en-us.html>
   and 102fr-fr
   <https://cdn.rawgit.com/w3c/uievents/gh-pages/tests/key-mtest-102fr-fr.html>
   .
   - These tests assume you have the correct physical keyboard and locale
      set.
      - Only keydown and keyup events are tested.
      - Only the 'key', 'code' and modifier flag attributes are tested.
      - Dead keys are not handled properly.
      - I couldn't completely verify the French keyboard tests since I
      don't have a physical French keyboard with me at the moment.
      - The tests pass on Firefox. Fail on all other browsers.
         - Chrome Canary succeeds if you disable the 'key' check in Options.

These tests are linked from UIEvent's main github page
<https://github.com/w3c/uievents> (near the bottom).

Please let me know if you have any suggestions for improving these
tools/tests.
