Breadcrumbs generated from 'Taxonomy: ID' argument are not properly translated using i18n

I ran across this niche issue while setting up a multilanguage site using the latest stable Image module to manage a large gallery. It turns out image_gallery.module uses Views to display the grid of thumbnails, and the imported View (image_gallery) activates breadcrumb generation by Views based on the Taxonomy term given as an argument.

Upshot is that the taxonomy breadcrumb logic in Views 2.x (nor 3.x from what I can see) is not looking to see if i18ntaxonomy is installed and enabled for the given vocabulary. This small patch against Views 6.x-2.11 checks for the module, checks the vocabulary to see if it's using i18n, and if so applies the translation to each term in the breadcrumb. The corresponding patch I offered up on the Image module side had to perform the same trick for the node page breadcrumbs in #870654: Image node page, gallery view and subgallery view breadcrumbs not being translated.

Reviews/critiques/suggestions are welcome! I have this up and running, but am always open to a better way to do something...
