Customizable node link text for the imagecache formatter

I'm not totally sure, but I think the customizable node link text is not only meant for lightboxes with image.module managed images but also for the imagefield/imagecache ones. Which would mean that t('View Image Information') in the imagecache formatter needs to be replaced with variable_get('lightbox2_node_link_text', 'View Image Details') so that the customized link text is also used there.

While rolling this patch, I also noticed that the 'View Image Details' occurrence in the admin form is not translated at all, and the occurrence in the JavaScript settings wraps a t() around the whole variable_get(), which makes this hard to translate because potx (or the former extractor.php) can't extract the string for translators. Wrapping the string itself inside the t() makes the translation for the default value more accessible and also makes the translated value appear on the admin form in case the translation has already been imported. While I was at it, I also did the same thing for the 'lightbox2_image_count_str' variable in addition to 'lightbox2_node_link_text'.

Hope you like it this way.
