function select_with_style_views_data_alter in Select with Style 7

Implements hook_views_data_alter().

Temporarily swap out the taxonomy term filter handlers used in Views.

This gets called when: o the widget type is changed on the Manage Fields tab of the content type o a View is saved o the caches get cleared

We could implement this in hook_field_views_data_alter(). However all hook_field_views_data_alter() implementations are called prior to any hook_views_data_alter() implementations, which means that we cannot place ourselves last via the module weight when competing with other modules implementing that hook.
