Return of the parcel table

A tentative to tackle #317 (closed). The Shipping > Parcels page now displays a table instead of a list of parcel widgets.

• The table gives minimal info on the parcels (status, linked proposal, name and number of items)
• For more details, the row can be expanded on click to display the parcel widget (as in the shipping tab of the investigation)
• The table has a search tool, meaning it can be used to search for parcels of e.g. a certain investigation, or status
• For small displays, the rows are replaced with the parcel widget.

I know it is not ideal as:

• There are redundant informations between the table rows and the widget
• One has to type the status in the search box when selection would be simpler
• For safety, changing the status of a parcel requires at least three clicks: expand, dropdown, select option.

Still, I hope it is a good start for #317 (closed).
