Move the key field to the website config

As of June 22 2016, the use of API key is required to access the
following:
- Google Maps JavaScript API
- Google Static Maps API
- Google Street View Image API

https://developers.google.com/maps/pricing-and-plans/standard-plan-2016-update

For domains accessing the API before June 22, it will still work without
an API key. Since Google advises to use the API key, we hide the Maps if
no API key is defined.

Migration of website module to new API.
The tricky phase is ir_http.py : we need to use `request.env`
only when the authenfication phase is done. Normally by
calling `super` of `_dispatch` method, but website module
required it to be done before. This is important since
`env`is a lazy property of `request` object.

Some hack were kept since this commit is a migration ('RequestUID'
in ir.http, ...)

Some docstrings were added.

[IMP] account: d'ont create journal items for invoice lines with quantity 0 (not amount because of tax)
[IMP] crm: usability kanban view and schedule an activity
[FIX] crm: schedule an activity bug when no activity yet
[IMP] website: app for website (not a menu in website admin)

This field is misunderdstood by common user and is problematic in saas
instances. Make it invisible, but usable with the html editor

-accounting, project, crm, mass_mailling, stock, point_of_sale, website, website_sale, sale

Easy solution: a binary field in website.config.settings

This additional administration group was formerly used to hide
the configuration menuitems for the common users.

Being manager should be enough to access these items

Users are tempted to enable all features they
see under the former "Speed" section of the
website settings, even if they have no idea
what they do.
One of them was `CDN Base URL` and had a default
value that was wrong and very likely to break
your website if enabled by mistake.

This commit replaces the default value with
a placeholder that looks more like a `sample`
URL, and makes the fields required when the
CDN option is enabled.

It also moves the whole "Speed" options to
technical features / debug mode.

Remove some duplicate config settings and improve
the layout of boolean options in various
config screens

The main button has classnames btn btn-primary.
Other buttons have classnames btn btn-default.
No more 'or' between the buttons.

In view inheritance, selecting an element based on the attribute `string` is
broken, since this attribute may be translated before the inheritance is
applied.  This fixes existing views to avoid such selections.
