Using file watchers under Windows Docker studios

A workaround is needed to make file change notification work under Docker for Windows:

# install Python via Chocolatey
choco install python

# install workaround Python script via PIP
pip install docker-windows-volume-watcher

# activate watcher workaround for all running Docker containers
docker-volume-watcher # leave running while you want watchers to work

Within any Habitat container/studio you want to use a watcher in, the stat and chmod commands must be binlinked for docker-volume-watcher's tricks to work

hab pkg binlink core/coreutils -d /bin stat
hab pkg binlink core/coreutils -d /bin chmod
