[mod2] Arrange amendments vertically when more than one line [was: Improve amendments ordering]

[RouxRC]

• Amendments should always be double ordered : by party then status, or by status then party
• The ordering by party should respect the order given in the groupes data, ordering by status should adopted ; neutral ; rejected
• When there are multiple lines of amendments in a same division, it would be much more readable if the ordered amendments would stack vertically first instead of horizontally as was proposed in the original mockup, and ideally start a new column every time we change status/party
• When loading the data, one of the two ordering should be applied immediately
