[FIX] [IMP] Second batch of fixes and small usability fixes/improvements for CRM...

email_template:
- fix email_template overriding recipients even when the template is void; the convention is that void values in the template are not used, meaning that they are not relevant in the template and not that they should erase existing values,
- added _order on name on email_template, in order to ease the choosing of templates,
crm:
- fix phonecall scheduling taking the lead/opportunity description as phonecall description,
- fix phonecall scheduling Chatter message: added phonecall description into it
- improved phonecall scheduling wizard form view (type is now on the left to ease reading and updating),
- fix opt_out parameter explanations; this parameter is relevant only for mass mailing and marketing campaigns,
- added 'Available for mass mailing' (opt_out = False) filter to give users the possibility of filtering leads before performing mass mailing,
res_partner:
- fix notification_email_send field missing on res_partner form view, preventing management of email reception policy for partners,
- fix opt_out parameter explanations (field added in email_template); this parameter is relevant only for mass mailing and marketing campaigns,
- added 'Available for mass mailing' (opt_out = False) filter to give users the possibility of filtering leads before performing mass mailing,
mail_message:
- fix read/unread filters on mail_message (help of both filters were the same; string of Unread becomes To Read to be clearer)
