Alist of checkbox types.

The cdr of each entry is an alist list three checkbox types for HTML export: on, off and trans.

The choices are:
  unicode Unicode characters (HTML entities)
  ascii ASCII characters
  html HTML checkboxes

Note that only the ascii characters implement tri-state checkboxes. The other two use the off checkbox for trans.
