Web Speech API Conformance Tests

I checked into the repository a slightly updated version of the Conformance
Tests.
https://dvcs.w3.org/hg/speech-api/raw-file/tip/conformance/index.html

Functionally, these are identical to the tests from
https://lists.w3.org/Archives/Public/public-speech-api/2012Dec/0001.html

The updates are to address recent changes in testharness.js, specifically:
- Use the new syntax to reinstate the long timeout.
- Loads scripts using same protocol as parent file (http or https).
- Change list: https://dvcs.w3.org/hg/speech-api/rev/4f41ea1126bb

As always, your comments and feedback are appreciated.
