Bring code style up to the latest standards
- This PR addresses code-style issues identified when testing the code against the WordPress Coding Standards.
The `-n` flag will ignore warnings completely, while often it is useful to see them and to fix them.
Using `--runtime-set ignore_warnings_on_exit 1` in the Travis script instead, warnings will be shown, both when a developer runs PHPCS on their own machine, as well as in Travis, but warnings will not cause a failed Travis build.
The `-v` flag will list each file being scanned. This is intended for debugging purposes and not needed for normal use.
As WPCS and PHPCompatibility were for a little while (May - July 2017) not compatible with PHPCS 3.x, the library tags cloned were previously fixed to prevent issues with that.
As both WPCS as well as the PHPCompatibility standard are now compatible with PHPCS 3.x, the changes made in PR 1110 and PR 1183 can be reverted.
Notes:
* PHPCS - use `master`.
WPCS uses a limited set of sniffs from PHPCS itself.
Most of these sniffs are long established, stable and rarely get updated, so using PHPCS `master` should be safe.
* WPCS - use the latest release `0.14.0`.
WPCS is the main source of CS violations and is under active development. This means that new versions of WPCS will easily break the build, so should be managed.
* PHPCompatibility - use `master`.
PHPCompatibility checks PHP cross-version compatibility.
It is actively developed and heavily unit tested, so any new violations found in `_s` because of changes in that library, should actually be addressed in `_s` ASAP.
The PHPCompatibility library became compatible with PHPCS 3.x and improved compatibility with Composer installs in version `8.0.0` which was a breaking change.
To account for that, the location where the library is cloned to and the `phpcs --installed_paths` command have been updated.

At some point in time, PHP was lagging behind and HHVM seemed like the future. What with PHP 7 being released and doing incredibly well, that time has passed and the popularity of HHVM is now marginal.
This commit drops testing against HHVM and starts testing against bleeding edge PHP nightly instead.
The new Trusty images as per Sept 7 include an image for PHP 7.2 (even though it hasn't been released yet).
The `_s` build tests are run against the lowest/highest supported PHP version for 5 and 7.
As `7.2` is now available, it should replace the `7.1` build.
If the file is called `phpcs.xml` or `phpcs.xml.dist`, it is automatically picked up by PHPCS.
A `phpcs.xml` is given preference over a `phpcs.xml.dist` file. So renaming the file to `phpcs.xml.dist` allows for people to use the file provided by `_s` if they choose not to add their own, but also leaves people the freedom to easily overrule it.
* Add PHP 7.1 to the travis test matrix as it will be released soon.
* Set `testVersion` for PHPCompatibility so we receive the messages for the right PHP versions.
* Include skip-link-focus-fix.js in the js hint/lint tests & fix up the file.
* Pull in .jshintrc from WP SVN.
* Add PHPCompatibility Sniffs.
* Sync the ignore statements to always exclude .min.js files.
* Slim down the tested against PHP versions even more.
What it will now do:
- Lint the php files against relevant PHP versions.
- Lint the js files once - the result won't change across PHP versions.
- Check against WPCS once - the result won't change across PHP versions.
What I have changed:
- Added linting against PHP 7 and HHVM, with HHVM being allowed to fail.
- Added js linting and style check per example from Twenty Sixteen.
- Moved to the faster container based environment for running travis.
- Script will no longer pull in PHPCS, WPCS and the JS linters in every build. Now they will only be pulled in when needed.
- Limited the clone depth for quicker cloning of external repositories.
- Removed the pulling in of WP and running builds against different WP versions as this wasn't used at all in the actual test scripts.
In short this updates `travis.yml`'s indent size to 2 spaces as per
WordPress' development repo and Jetpack.
Inserts final newline.
Uses a period at the end of each sentence.
