[FIX] mail: translate tracked fields name in chatter

Status tracking messages are not translated into user's language while updating any document with tracked fields (opw 612847)
[IMP] website: google analytic - use Automatic Cookie Domain Configuration.

Automatic Cookie Domain Configuration simplifies cross domain tracking implementations by automatically writing cookies to the highest level domain possible when the auto parameter is used. When used on the domain www.example.co.uk, it will try to write cookies in the following order:

co.uk
example.co.uk
www.example.co.uk
Analytics.js will fail to write a cookie on co.uk but will succeed on example.co.uk. Since a cookie was succesfully written on a higher level domain, www.example.co.uk will be skipped.

[FIX] web: webclient_bootstrap: render the menus when the user is really a user

The webclient rendering is done in two parts: the server renders the boilerplates
including the menus, and then the  javascript launch the webclient using the
server-side boilerplates. In some case, we want to render the boilerplates but not
the menus (auth_calendar). Added groups around the t-call to the menu in the web
template. Fixes issue #2044.
