JavaScript file when opening the OpenDC web UI which contains the
configuration of the web app.

This change addresses #137 which reports that machines on shelves lower
than the top shelve cannot be accessed and doing so will cause the UI to
disappear and an error message to be generated.

The issue was caused by using the incorrect logic for selecting the
machine at a certain rack position.

Fixes #137

This change updates the source structure of the OpenDC frontend to
follow the page structure.
