Update "change slide" behavior from presenter view

[GildasMorel]

Dans la presenter view, ne plus synchroniser la gesture slide sur le cadre représentant la vue on stage avec le changement de slide effectif sur la stage view.
Ajouter un bouton qui, au clic, effectue le changement de slide sur la stage view en prenant comme information le numéro du slide affiché par le cadre représentant la vue on stage de la presenter view.

De cette façon, on peut skipper des slides si on voit qu'on est en retard par exemple.

Le speaker sélectionne le slide qu'il souhaite afficher sur la vue on stage et appui sur le bouton pour l'afficher directement sur la vue on stage.

Final tech proposition for first attempt to resolve this issue :

Add "start asynchronous navigation switch" plugin

The plugin displays a button : "Start asynchronous navigation".

When the user click on this button, it :

• displays 2 new buttons : Cancel and Validate
  The Cancel button synchronize the presenter view with the on stage view state
  The Validate button synchronize the on stage view with the presenter view state
• send an event to the server, so the server can save in his store the asynchronousPresenters value to true.

tc-controller should know that it controls a presenter layout

In its init method, if the tc-controller controls a presenter layout, it should send to the server the information, so the server save its socket id in its store in the field "presentersList" .

In the broadcastStateChanges, if the value asynchronousPresenter is set to true, the server gets the ids stored in presentersList to retrieve the recipients of the goToSlide event.

The eventBusResolver method "emitTo" needs to evolve to handle an array for the "target" argument.

The emitTo emits an event to each recipients mentioned in the target array.

New onStageState in server store

When the asynchronousPresenters value is set to true, the onStageState in the store is set with the currentState value.

It represents the state of the on stage view.

When the "Cancel" button (see above) is clicked, the asynchronousPresenters is set to false and the currentState is replaced by the onStageState value. The onStageState value is emptied.

When the "Validate" button (see above) is clicked, the asynchronousPresenters is set to false and the onStageState value is emptied.

Option

Add a new button on presenter mobile layout that goes to next slide when clicked.
