Improve automated packaging (#221)

Upload alpha releases to testpypi (when an alpha tag is pushed - workaround for pypi not hosting pre-releases).

Upload real releases to pypi (when a release tag is pushed).

Also added a non-dev conda package build, which will be uploaded to pyviz main when a release tag is pushed.

Will need to enter param's pypi credentials into travis for this to work when a release tag is eventually pushed.
