[REF] web,*: ActionManager/ViewManager refactoring

This rev. is the first part (out of 3) of the refactoring of the
ActionManager and ViewManager layer of the webclient.

The main changes are:
  - there is no ViewManager anymore, its work is now handled by the
    ActionManager itself, but isolated in a specific file ; this
    eases a lot of things, as the breadcrumbs handling for example.
  - the ActionManager code is converted to the new coding principles
    and guidelines ; mainly, children widgets communicate with it by
    triggering events up, and not by function calls anymore.
  - the ActionManager layer is now testable, and a lot of tests have
    already been written.
  - the code in other addons has been adapted consequently.

What's coming next:
  - introduce the 'AbstractAction' Widget, and make client actions
    and view controllers inherit from it ; this widget will
    implement a common API that could be used uniformly by the
    ActionManager (e.g. restore(), canBeLeft(), renderButtons(),
    getTitle()...).
  - move the ControlPanel handling from the ActionManager to the
    AbstractAction.
