[FIX] website: do not restore page views
[IMP] improve graph view layout and groupbys

* add a 'total' foldable button to allow the user to control the column
in pivot table view
* in the dropdown menu, add all fields from the model instead of only
those from the search view groupbys
[FIX] correctly type date field in crm_lead_report

opening_date and date_closed were cast to char but are supposed to be
dates.  When you try to group crm_lead_report by one of them, postgres
was not happy.  Now, it properly tells postgres that they are of type
date.
[FIX] correct various date issues in reporting

* remove old 'day', 'month', 'field' and replace them by the actual
date/datetime field
* remove weird cast to char when creating the view to prevent crash
when grouping on them
* remove duplicates (such as 'creation_date' and 'create_date')
* fix typing errors (field type date defined as a datetime in the
postgres view)
* fix search view definition

[FIX] sale: config, timesheet if module account_analytic_analysis

In Settings > Sales, the onchange_timesheet ensure that if you check timesheet, it checks module_account_analytic_analysis.

Therefore, if module_account_analytic_analysis is installed, timesheet should be checked by default
Until now, it worked "luckily", because the onchange_timesheet of the field module_account_analytic_analysis was triggered before the onchange_timesheet of the timesheet field. Nevertheless, we shouldn't trust the onchange calls order.

[FIX] account_voucher: avoid trying unreconcile a move twice

When we cancel a voucher, we may be trying to unlink a reconciliation that was already removed on another move (just looking at the version in cache). In such cases, the unlink would fail with traceback. opw 610287
[FIX] project_long_term: avoid bad duplication of phases

When we duplicate a project, the related phases need to be duplicated as well but keeping references between each other.
e.g. 'project 1' with 'phase A' follwed by 'phase B' should become 'project 1 (copy)' with 'phase A (copy)' followed by 'phase B (copy)'.
