- no config overrides - now all set in environment
- use different files for staging and live too allow for differently named env variables
- updates to run_app and run_tests scripts to set correct environment (test/development) so correct config picked up
- use environment file on deployed environments to pick correct config
Similar to how PEP8 enforces Python style, there are tools for front end code:
- jshint[1] for Javascript
- sass-lint[2] for SASS
This commit adds the Gulp plugins for both, and sets up some sensible rules
(which can be iterated on).
It also adds a command to `./scripts/run_tests.sh`, so that any errors in the
front end code will fail the build before it has a chance to be deployed.
