Changes

Gradle: Bootstrap from miniconda, including graphviz.

This relieves the dependency on a system GraphViz, and we can use a
pre-built Python.
 (commit: cafa1db)

WIP: Setup Anaconda directly from the build script.

This attempts to avoid the python envs plugin. The idea would be to get
a Miniconda installer via the regular dependency mechanism, install
miniconda and then install an environment from an environment.yml into
which we can then install macrogen.
