[IMP] web: easy selection of a period in filters menu

This commit allow to create easily a range of periods (related to a field
of date or datetime type) to select in the filters menu.

Two new attributes on elements with tag 'filter' are now usable
in combination in a search view arch:

- date: string.

		A valid field name with associated type date or datetime

- default_period: string (optional).

		To choose in the following list:
			- 'today'
			- 'this_week'
			- 'this_month' (default)
			- 'this_quarter'
			- 'this_year'
			- 'yesterday'
			- 'last_week'
			- 'last_month'
			- 'last_quarter'
			- 'last_year'
			- 'last_7_days'
			- 'last_30_days'
			- 'last_365_days'

Example:

<filter string="Creation Date" name="period_generator" date="create_date" default_period="this_quarter"/>

Note: the attribute 'domain' can not be used for such filters.
The generated domains are dynamic and can be saved as such
via the favorites menu.
