Release version 1.0.12.

[bigeasy]

Once again; here is the release checklist mentioned in #140.

• [x] Ensure that all the features, including updated TZ databases have already been committed to master before performing a release. Do not add new code in a release commit.
• [x] Ensure that your change log is up to date with all the changes prior to 1.0.12. Do not edit the change log a bunch in a release commit.
• [x] Create a git checkout -b release-1.0.12 branch.
• [x] Checkout your release-1.0.12 branch.
• [x] Update the version number in src/timezone.js to 1.0.12.
• [x] Update the version number in t/version/get.t.js.
• [x] Update the version number in package.json.
• [x] Ensure that the CHANGELOG looks reasonable.
• [x] Run make clean && make zic && make && npm test.
• [x] Run git commit -m $'Release 1.0.12.\n\nCloses #289.' -a.
• [x] Get the date of the commit and add it to change log.
• [x] Run git commit --amend -a.
• [x] Close this issue with that commit message.
• [x] Run git tag v1.0.12 && git push origin v1.0.12.
• [x] Merge release-1.0.12 into master with git checkout master && git splice release-1.0.12.
• [x] Push master.
• [x] Wait on Travis CI build to pass.
• [x] Run make publish which will clear out .AppleDouble and .DS_Store before publishing and publish the build directory.

Publish data files to gh-pages.

• [x] Go to your checkout of the gh-pages.
• [x] In the code submodule run git fetch && git checkout v1.0.12 && git submodule update.
