[FIX] context_timestamp MUST return a "timezone aware" timestamp
[IMP] calculating nextcall datetime of a cron SHOULD use the cron's user
[FIX] base: revert 19e401a for title on res.partner form

The title of the partner is restricted with a context that will change in the onchange_type. Having twice the same field will not work well.
Remove the invisible attribute as the domain is handled by the domain.
[FIX] purchase: add purchase_order_count in kanban for purchase users only

No need to set account.group_account_manager for the field supplier_invoice_count, as account.group_account_manager implies account.group_account_user
[FIX] mail: when having only mail installed, do not show any 'share with my followers' compose box. This comes only with hr, for the inbox. This was probably forgotten when updating the mailboxes hr-goal and hr-related gamification / chatter stuff.
[FIX] mail: posting on the user should be redirect to its partner, not nowhere.
[FIX] mass_mailing: fixed label of ab testing not displayed in mailing
form view when not using campaigns; however this option should be displayed.
[CLEAN] mail_message: removed an unused import
[FIX] portal_sale: remove un-necessary access rights, improve rules

Portal access rights need to be associated with
security rules, or not granted at all, as soon
as they grant access to non-trivial data.
[FIX] portal_sale: remove more access rights, add pricelist access

Pricelist access is necessary for being able to read
the unit price of sale order lines, and does not
pose major security risks, as it does not permit
reading the actual pricelist definition.
