Implement title alignment

This adds support for `i3 4.16`'s ability to set the title alignment.
The command is `title_align left|center|right`.

When the title is on the right, marks are moved to the left. Otherwise,
they are on the right.

*unmark* [<identifier>]
*unmark* will remove _identifier_ from the list of current marks on a
