[IMP] crm, website_crm: replace support of activities

crm.lead model now supports activities. Filters have been added to ease
their management. Mail activities replace the old crm.activity model. All code
related to crm.activity is then removed, including views and custom widget.
Standard activities feature is now used widely in Odoo addons and replace
those custom activities.

A small update is required in website_crm_partner_assign. Now the portal user
can only update or create its own activities aka assigned to him. If he has
an activity assigned to him it is displayed in the opportunity website view.
If not editing the opportunity will create a new activity assigned to him.
