🚀(scalingo) add Scalingo deployment scripts and fix frontend build

This commit, with contributions from Sylvain Grizard, adds support
for PaaS deployment platforms such as Scalingo, which build the
project on commit. It uses the La Suite Buildpack, which compiles
the frontend first as static files, and serves them along with
the backend with nginx.
