Extend theme_render_attributes() to views template files

The work done with theme_render_attributes in order to bring all attributes into preprocess is awesome and makes life so much easier. The idea is to bring all of this functionality into Studio by providing the default views template files along with the needed preprocess functions. None of the default views classes will be removed, only moved into preprocess.

This will allow for infinite control over all attribute output within views template files through preprocess. The addition and removal of classes can then be handled through preprocess without the need to create additional template files.
