#369765 by joachim: add an option to load data in to the $node object; also indexing terms array by $tid to match taxonomy data.

Initial commit of a small helper module that provides display options for taxonomy terms on node pages. Options are:

* default (do nothing),
* list (remove from the standard display and instead display as a list),
* custom (remove from the standard display and instead display as a comma-separated list),
* none (do not display)
