Release Candidate 0.16.3

[nicain]

This will be the last pull request merged for the 0.16.3 release

While preparing a release:

• Create a Release Epic on ZenHub that will track the release issues and pull requests
• Create a "release candidate" branch, and push to main fork (https://github.com/AllenInstitute/AllenSDK)
• Create a draft pull request for the release (i.e. Release Candidate 0.16.2)
  • Assign this draft PR to the Release Epic
  • Assign a developer to be responsible for the release deployment
  • Add the Project Owner as a reviewer
  • Copy this checklist into the draft pull request description

After each major change to master:

• Update CHANGELOG.md: https://github.com/AllenInstitute/AllenSDK/blob/master/CHANGELOG.md
• Update "what's new" section of index.rst, if needed
• Rebase the release candidate branch, and force-push to the main fork

When you are ready to release:

• Prepare the official release commit
  • Bump version by updating version in init.py
  • Add the release date to the CHANGELOG.md and index.rst files
  • Change the draft to pull request to "ready for review"
  • Code Review with the Project Owner
  • Merge when it is ready; this will generate a merge commit, and this commit will be the official release commit.
• Confirm that this official release commit passes all continuous integration:
  • python{27/36/37} Build Plan
• Create a Release: https://github.com/AllenInstitute/AllenSDK/releases <"Draft a new release" button>
  • Create a draft release
  • Review the release with the Project Owner
  • Publish the release

Publish:

• Push to pypi
  • python{27/36} Deployment Plan
• After release/deployment, merge master back into internal
• Create a new page for the release notes on the wiki: https://github.com/AllenInstitute/AllenSDK/wiki
• Announce release on https://community.brain-map.org
• Announce release on https://gitter.im/AllenInstitute/AllenSDK
• Update release instructions

Looks good.

@NileGraddis I havent merged this PR (the resulting merge commit will be the release commit) because I have been waiting for a branch build to finish: http://bamboo.corp.alleninstitute.org/browse/IFR-AAG18-1

When this branch build is G2G, can you take over and cut the release?
