function workbench_access_views_pre_view in Workbench Access 7

Implements hook_view_pre_view().

Dynamically adds the exposed fitlers that workbench_access provides to appropriate Views.

There are a lot of 'if () {} else {}' statements in here to find out which options to target. These look at a given option and check if it uses the default settings or an override. The given option is then modified to add filters/fields/settings from workbench_access.
