Defined in tcl/intranet-defs.tclUsed as security for category-list, category-add, and category-edit and edit-2
in employees/admin.
We use these generalized pages to manage several subsets of the categories table,
but to avoid url hackery that would access other subsets, we define the allowed
subsets here.
category_html is a plural pretty-name that is both displayed on the page and passed
in the url. category_type is its corresponding column data in the categories table.
Ideally, these subsets should become their own tables and this proc should be
obsoleted.
