Item matrix templates

[ociu]

As in #9, apply templates also to the item-matrix nodes, so that the whole table format can be customized, even not being presented as a table.

One of the consequences of using templates for item-matrix is that the item-list directive would be no longer necessary, as a particular template could be defined to show only one part of a traceability matrix as a list. This would also allow more complex lists, such as lists with sublists.

Template would not only have as input the related items, but also the implied relationships, so that relationships could be also shown in the output.

Example template: item matrix as is generated now:

.. list-table:: {{ title }}
   :header-rows: 1
   * - Source
     - Target
{% for line in table %}
   * - {{ line.source }}
     - {{ line.target }}
{% endfor %}

Another benefit is that this way, table generation code would be much, much simpler.
