function FilterFormatAccessTest::testFormatWidgetPermissions

Tests editing a page using a disallowed text format.

Verifies that regular users and administrators are able to edit a page, but not allowed to change the fields which use an inaccessible text format. Also verifies that fields which use a text format that does not exist can be edited by administrators only, but that the administrator is forced to choose a new format before saving the page.
