Build anaconda installers in CI using conda constructor and attach them to the respective github release
Getting a working set of packages in an installer is not trivial due to very delicate package specification resolving and sometimes incompatible packages across defaults and conda-forge channels.
Currently what seems to work is to have package specs relatively loose on Windows for Appveyor but very rigid on Linux/OSX in Travis.
To update the static package lists for Travis, use the only_install_conda_package_and_test branch and then paste those package lists into the respective recipes on master.
Built installers will be tested and deployed to github releases.
