In the future, we want to allow users to rely on third-party services
for data storage, such as hosted MySQL and such. To do so, we need to be
able to configure the host/port of these services, which we do here.
This is to address part of #114.
It was tricky to define correct settings: the "localfs" default storage
backend was causing incorrect urls of the form "/media/<id>/<name>.csv".
Close #143
Configuration values can be loaded from the system environment by adding
a "TUTOR_" prefix.
Environment values supersede values from the user configuration file, so
that we can set values from the command line with "KEY=VAL tutor config
save --silent" even when KEY is already present in the user
configuration file.
We had to backtrack from the latest release of the
android app, which is not compatible with the mobile api v0.5 available
in Hawthorn. This should change in ironwood.
Also, we included the correct oauth client ID in the app, which
prevented communication with the LMS.
The android app is now out of beta \o/
Close #89
Replace all make commands by a single "tutor" binary. Environment and
data are all moved to ~/.tutor/local/share/tutor. We take the
opportunity to add a web UI and revamp the documentation.
This is a complete rewrite.
Close #121.
