l2: show which column sorts and in which direction

Browse Source 
Clicking a heading sorted the table but nothing said so afterwards - the
only feedback was the rows moving, which is no help when the sort key is a
column you are not looking at.

Give every sortable heading a permanent marker: a neutral double arrow when
it is not the sort key, up or down when it is. The marker sits in its own
span so the i18n pass, which replaces the heading text, does not wipe it.
