[FIX] login: look at the value of action_id on the current res.users to execute the action instead of the first link (Inbox). Bring back 6.1 behaviour.
[IMP] always click on first link to have menus and breadcrumb
[FIX] web_calendar: Do not display empty values in displayed text in calendar view cells
[MERGE] [FIX] home action: fixing the broken field 'action_id' on the res.users form (lost with 6.1->7). This field executes a custom action at page load.
