Subject: [PATCH] feature #660258 by marvil07, franz, dixon_: Expose widgets as views fields.

This add support for the three vud_* submodules in the following way:

- vud_node: let you add a vud_node widget on a node view showing one
            widget per row.
- vud_comment: let you add a vud_comment widget on a comment view showing
               one widget per row.
- vud_term: let you add vud_term widgets on a node view showing one
            vud_term table per row. this is because vud_term vote tag
            depend on one nid.
