[snapshot-2017] Candidate modules for inclusion

[svgeesus]

As requested by @dbaron on 2016-12-21 CSS call. All modules (CSS and fxtf) sorted by already-there, will-include, and the rest.

https://github.com/w3c/csswg-drafts/blob/master/snapshot-2017-modules.md

I made an edit to that list to fix one duplicate I caught.

Looking through the list of things that aren't included, I think things worth considering to add to the "fairly stable but beware" level (although I'd probably lean against inclusion on some of them) are:
css-align
css-grid
css-ruby
css-text
css-writing-modes
filters-1

We should also think about whether things like cssom, cssom-view, and the houdini specs should be part of a snapshot if they're stable enough.

I see no reason not to, if they are stable enough.

@dbaron I agree on your list of fairly stable but beware specs (maybe not ruby), but how about also including css-break? implementation is somewhat spotty, but the spec itself seems to me to be in good shape, and quoting the introduction:

The primary audience is CSS implementers, not CSS authors, as this definition includes modules by specification stability, not Web browser adoption rate.

Also, snapshot 2015 promises that indices of properties, functions etc are coming:
https://www.w3.org/TR/CSS/#indices

Snapshot 2017 should link to the specific sections:

2 Properties and Descriptors
3 Property/Descriptor Values
4 Functions
5 At-Rules
6 Selectors

because the indices are not well known at present.

We just discussed in the WG meeting, and concluded:

Add to primary section:
Writing Modes

Add to rough interop section:
Variables
Text

Add to completed design section:
Align
Grid
Filters
Break
