[IMP] web: module can be asynchronous loaded if it return a deferred

Each module can return a deferred. In that case, the module is marked as loaded
only when the deferred is resolved, and its value is equal to the resolved value.
The module can be rejected (unloaded). This will be logged in the console as info.

Remove if_dom_contains from the website, the modules return a rejected deferred if
the DOM doesn't contains the seleted values.
