Conversion of ORTC API specification to contiguous mode

Respec (the Javascript library used to produce W3C specifications) has deprecated the mode of operation we had been using to produce the ORTC API specification, producing a warning for both the current as well as previous versions of the specification.

As a result, we have been working on converting the specification to "contiguous mode", following the lead of many other W3C WGs and CGs.

With help in the conversion from the W3C staff (thanks Dom!) and manual fixing of many, many remain issues, we now have a draft version of the specification that renders with no errors or warnings:
http://internaut.com:8080/~baboba/ortc/github/ortc2b.html

This version is now checked into the ORTC Github as "ortc2.html".

The original version (which should be identical in content) is here:
http://internaut.com:8080/~baboba/ortc/github/ortc.html

As usual, this is checked into ORTC Github as "ortc.html"

There are still a few steps to take before officially adopting the converted specification:


1.       Checks to make sure that no unintended changes have been introduced.  I have gone over the specification many times now, but it is quite possible that I've missed something in my visual inspection (diffs are virtually useless since the conversion process introduced hundreds of changes).

2.       Application of tidy (since the conversion process has left the specification very messy)
