frontends (xmlui): added a user_action attribute:

this attribute indicate if the data is a result of a user interaction or an event from the backend (in the later case, the frontend can choose to avoid interrupting the user).
Internally (in XMLUI), "FROM_BACKEND" is added to XMLUI.flags if the UI result from a backend event.
