Honor "staleTabIds" property from /rest/api/window/commit response

[teosarca]

We are going to introduce "staleTabIds" property (optional) on /rest/api/window/commit responses.

It will contain a list of tabIds that become stale and you need to refresh them.
The property will be present only when needed.

First case we are trying to solve with that:

• create a sales order
• add some order lines
• complete the sales order
• backend story: some underlying APIs generated more order lines for that sales order and we need to also show those to the user
• in this case we will mark those tabs as stale.

Example:

After refreshing the page, it looks like this:
(remark that we have now 2 order lines!!!)

It would be nice, in case the tab is not visible to just schedule a lazy loading.

About lazy loading, i've created a new issue to gather ideas: #130
