Bunch of modules converted to CommonJS.

Missing features:
- code save
- original code override
- orchestration is buggy
Better default layout and CodeMirror style.
Elevators are working.

Needs to:
- save code states in localStorage
- check run completion
- identify stalled elevators (something to do but state idle)
Cosmetic adjustments.
Dealing with scenario reset

- handling only with positioning transition
- clearing columns when no scenario is set

Scenario completion
Rethinking a bit the stack shift.

- we shift the destination as we move
- we don't check the currentLocation as we request a floor, as it might change as we progress amongst the stack
goToFloor -> moveTo
requestsStack -> requestedAt
Tests are now commonJS compliant
Best GIFs ever
Fixed karma setup
Cleaning the deploy process.
CSS bundle.
