translate node types

See my comments here: #602668-1: Translate the node type token

Marked #590346: content type name translation duplicate.

function_exists() is surely faster than module_exists(), so I would still tend to go that route.

really? module_exists uses module_list's static cache. And module_list is called all over the place. In fact, I'm the one who suggested for these related patches to use module_exists. And array_key_exists() has to be way faster then function_exists() assuming the module comes out of the static cache.

A call to function_exists() isn't as self-documenting as a call to module_exists(), and as the call is not in a critical path and as the speed difference is not significant, I favor module_exists().

I was asked at http://drupal.org/node/394728#comment-3145722 if this issue could be moved to Apache Solr Multilingual.

Like I pointed out at http://drupal.org/node/436578#comment-2829254 it has to be solved in Apache Solr Search Integration itself.

ok, so let's get it done.

Based on http://drupal.org/node/609364 and http://drupal.org/node/304002 this seems like a sensible way to do it.

Applied to 5--2, 6--1, and 6--2. Didn't commit to HEAD as I don't know how tt() changed in D7.

Create issue in Facet API queue if still an issue.
