• task #818500: widget documentation to asciidoc
• task #821048 by marvil07: Make widgets easy to theme.

  - update vud_widget arguments on hook_theme().
  - we do not have standard theme overwrite so, generalizing a pseudo
  theming function for widgets and votes: vud_pseudo_theming(), to reuse
  it on both proxy functions. We do that in this way:
  - let modules modify variables passed to the template
  - and then provide template suggestions by hand. so, stop providing
  function suggestions at theme calls, now we are using a mimic of
  template suggestions. we are not using direct theme templates because
  is not possible to decide dinamically the path where the template is
  located(in contrast with function names and template names).
  - for this change create and implement hook_template_suggestions() on vud_* modules
  - no more need to use implement hook_theme() on vud_* modules.
  - fix: define vud_votes theme hook once at vud.theme.inc
  - remove vud_theme_functions() an update theme calls accordingly
  - document all this changes!

• 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.
