CRC_cntrl_QryTool.js adds quotes to enumerated text values

Query-by-value fails to find observation-facts because an quotes are inserted into the SQL where clause. For example, rather than "where tval_char = 'Malignant'" the SQL is generated as "where tval_char = '"Malignant"'

The fix is to remove the quotes from line 518:

sEnum = '("'+sEnum+'")';

remove extra quotes -- change lin e 518 to

sEnum = '('+sEnum+')';
