Proposed a CSVW Community Group - please vote in support

As discussed on the call (as well as last year during the templating
debates) I've just proposed a W3C Community Group for CSVW. It needs five
votes of support before it is confirmed - please vote :)

I kept the description pretty high level (and non-committal w.r.t.
"support" vs "mutual support"), and shared a few more comments in the
associated blog post that announced the proposal.

"CSV on the Web <https://www.w3.org/2013/csvw/wiki/Main_Page> collaboration,
discussion and mutual support for implementors, publishers and spec
developers. Focus is on W3C’s CSVW specs but also on related work e.g.
R2RML, potential extensions, errata and test cases."

Our previous discussion of a community group was much more restricted (see
https://lists.w3.org/Archives/Public/public-csv-wg/2014Nov/0028.html). I
prefer this approach, which basically gives us a single mailing list,
avoiding premature fragmentation of discussion.
