[IMP] stock: improved the algorithm of automatic color selection for picking types... Err.. 'usability improvement', i guess...
[REV] stock: removed feature that was looking if a procurement was in exception (because all its moves were cancelled) at the time of _run_move_create and which cancel the previously made attempt (to avoid duplicates). The reason of this removal is that it may have side effects, and that we prefer let the users manually fix exceptions (dixit fp)
[IMP] stock, usability: added sequence field on stock.picking.type to allow a user to sort the kanban of 'All Operations' and set default sequence ot have 'receptions-internal-pick-pack-ship'
