add primitive support for fixed header values.  fixed headers can be given as a comma- or whitespace-separated list of values. they will serve to both limit to results to the given values (something that could just as well be done with the WHERE clause, but I figured people would want this behavior) + force all given values to be included, even if it causes empty rows.
 * add support to GroupDataProcessor + relevant RPCs in Django to support fixed header values, but *only* for single headers (i.e. no composite header support)
 * add text box to GWT spreadsheet UI, accessible only in single-header mode. box accepts comma- or whitespace-separated list of values.
 * add necessary code to process fixed headers + pass them to server, and to store in history URL
