This is for supporting json-based plugins. The great thing about this
change is that it allows us to easily print plugin version numbers in
`plugins list`.
We are facing the following issues in CI:
$ ./dist/tutor --version
[5201] Failed to execute script pyi_rth_pkgres

Otherwise, tutor-openedx will be pulled from pypi during plugin install.
This was failing because the latest pypi release was not installing
correctly (see #261).
All existing plugins are added to the binary bundle, in their latest
version, so that users don't need to pip install tutor.
Also, the tutor MANIFEST.in file was removed to simplify the management
of package data.
Close #242.
Thus, we remove the -y/--yes options, which were kind of unintuitive,
and we add instead `-i/--interactive`. The quickstart commands remain
interactive by default, but can be silenced with `-I/--non-interactive`.
The "latest" tag is a pain to maintain: it's a tag that we delete and
re-create at every release. Whenever we delete it, the binaries become
unavailable on Github until they are re-generated. Thus, from now on, we
conform to good practices (as examplified by the
github.com/docker/compose) project and distribute only pinned release.
The "nightly" tag remains, for now, as it allows us to distribute beta
features. It may disappear in the future.
For some reason, the "nosetests" binary is not available on Mac OS in
Travis-ci. This is what we get when we try to install nose:
Requirement already satisfied: nose==1.3.7 in
/usr/local/Cellar/numpy/1.14.5/libexec/nose/lib/python3.6/site-packages
(from -r requirements/dev.txt (line 25)) (1.3.7)
Environment is no longer generated separately for each target, but only
once the configuration is saved.
Note that the environment is automatically updated during
re-configuration, based on a "version" file stored in the environment.
