PURPOSE
Display the activity type through the icon of the widget and change the place to
display to whom the activity is assigned (if it is not assigned to the current
user).
SPECIFICATION
Display the deadline with a prefix as responsible if the activity assigned to
another user than the current one (uid).
Add a new 'activity_type_icon' field to the mail mixin to get the 'icon' of the
type (fa-phone, fa-users, etc...) and for the list_activity widget, display it
as an icon instead of the default 'fa-clock-o' icon.
