New query in OrderDAO to get projects filtered

The new query receives several params from the filters (dates, labels, criteria,
customer and state) and returns the filtered orders.

For the moment it's only used to get the initial list of orders for the projects
list window.

Use new database query when filtering projects list

The database query that filters the orders by several fields is used only when
the subelements checkbox is not clicked. Otherwise the old query is used and the
old behavior is kept for the filtering.

However, if the checkbox is not clicked, the new query is used to get the
initial list and to do the successive filtering too.
