Timing of version 2.0.0

[jrfnl]

I previously proposed to drop PHPCS 2.x support and remove all deprecated sniffs by end of August - largely with an eye on being able to have a different namespace to prevent clashes with the WP project itself.

I'd like to propose changing that deadline to end of December 2018 for the following reasons:

1. WPCS 1.0.0 deprecates a number of sniffs which we'd want to remove in v 2.0.0.
2. WPCS 1.0.0 contains breaking changes, most notably the re-categorization of a number of sniffs.
3. At this moment, it doesn't look like WP Core will drop PHP 5.2/start using namespaces within the next six months, so the namespace reason is less urgent.

As there are numerous standards out there which have WPCS as a dependency, we ought to allow them some time to adjust their standard. and two (summer/vacation) months does not really sound long enough, which is why I'm proposing moving the 2.0.0 release back to the end of the year.

Opinions ?

FYI: I've prepared most of the changes needed for WPCS 2.0.0.
Once WPCS 1.2.1 is out of the door tomorrow, I will start pulling commits cherrypicked from my WIP branch. Expect something like 30 to 40 PRs to get all the changes in.

After some discussion, @jrfnl and I plan to do a 2.0.0-RC release in the middle of next week, once the change log is done (most of the 2.0.0 code changes are now done), and then follow that up with a 2.0.0 release in early to mid January.

FYI: I've trailed through all the PHPCS 3.x changelogs up to 3.4.0 for any other changes WPCS could benefit from and opened issues/PRs for what remained. Aside from the changelog and some minor documentation updates (and the currently open PRs), as far as I'm concerned WPCS 2.0.0 is done.

Might be worth it to have a look at the older open PRs to see if any of them can go in and to trail through open issues to see if there are any which can be closed (or addressed as quick wins).
