Merge pull request #6 from tidoust/scope

Refined scope: no protocols, possible guidelines, interoperability defined
Added PING, Web Security IG and WebRTC to liaisons list

The charter mentions privacy and security issues. As such, reviews by the
Privacy Interest Group and Web Security Interest Group are strongly
recommended.

I added the WebRTC group as well in the list of groups that develop
specifications that are potentially relevant for implementors of the
Presentation API, e.g. for extending the API to support use cases that
the group will not address per se (such as content mirroring).
Added somewhat realistic milestones for the Presentation API

The milestones take for granted that the Working Group would be
chartered for about 2 years.
Updated mailing-list name to avoid conflict with CG
Added sentence to allow splitting functions into multiple specs
Clarified CC-By and W3C Document License dual-licensing rules

The section is mostly a copy-and-paste of the end of the Document
License section of the HTML WG charter:
http://www.w3.org/2013/09/html-charter.html#documentlicense
Dropped charter authors "TBD" section
Updated URL of group's home page for consistency with mailing-list name
Merge pull request #7 from tidoust/liaisons

Updates to liaisons, milestones, document license and mailing-list name
Define application-specific media.

Merge pull request #8 from mfoltzgoogle/gh-pages

Define application-specific media.
Merge branch 'gh-pages' of https://github.com/webscreens/charter into gh-pages
Incorporated Wayne's suggested changes

- Up to 2 F2F meeting per year (was 1) are now possible on top of F2F at TPAC
- Presentation API description updated, using same wording as in scope section
- Added @@ next to the link to the CG report. Also clarified that the report
is a final report. This needs to be updated before the AC review, either with
the link to the final report if it is published or with an explanation that the
CG is about to finalize the report otherwise
- Dropped mention of Last Call for the test suite as that step is likely to
disappear in a near future
- Updated expectations re. CG focus after WG creation and clarified the need
for a Dual License accordingly
- Clarified the overlap with the NSD API and the expected outcome of the
liaison with the Device APIs WG.
