[IMP] website_*: Improve menus and configuration

Purpose
=======

Clean menus structure in website frontend and backend, for an easier navigation.

Specification
=============

Website
-------

- Restructure menu
- Enterprise: Keep google analytics view in a dedicated menu item when ecommerce is
  installed:
    - Sales Dashboard(ecommerce dashboard)
    - Analytics (google analytics)
- Community: Keep both sales orders and google analytic dashboard on the same
  dashboard view
- Restore google analytics api option in website settings when ecommerce
  is installed

E-Commerce
----------

- Website > orders > orders: add default filter "from website" and remove it in
  the action. That way if you create an order manually there is still a way
  to find it from the menu (the salesteam is different)
- Default filter for abandoned cart menu
- Improve setting text and tooltip. It's not obvious that recovery emails must
  be sent manually. Replace with:
    - Title: Abandoned Carts
    - Subtitle: Send a recovery email when a cart is abandoned
    - Tooltip: Abandoned carts are all carts for which no transaction has
               been confirmed while the customer has filled in their address.
               You can find them in *Website > Orders > Abandoned Carts*.
               From there you can send a recovery email to stimulate the
               customers to resume their order.
    - Tooltip email template: This email template is suggested by default
                              when you send a recovery email.
    - Tooltip hours: Carts are flagged as abandoned after this delay.
    - Hour label: Cart is abandoned after .... hour(s).
