v 0.17.0 Release

[drwelby]

With the next release, the following packaging changes should be made:

• Conda recipe uses noarch: python but specifies Python build versions in build_config.yaml. Because of the noarch declaration the build versions are ignored.
• Python 2.7 needs to be checked. It still works in with the Pip packages
• related: need to drop Python 2 support soon, might want to warn on import
• the build: requirements section is completely wrong, it's for dependencies needed to build the package, not go in the package.
• the recipe syntax is out of date and needs to be checked anyway.

Dependency problems:

• scipy.misc for imread has been moved to imageio, need to check that import in tmsimage.py

Internally, this release should:

• Add the use_template work in dev
• get rid of the deprecated methods we've warned about.
