+- Oracle url translation was broken, fixed, will feed host/port/sid
+into cx_oracle makedsn() if 'database' field is present, else uses
+straight TNS name from the 'host' field

- count() function on selectables now uses table primary key or
first column instead of "1" for criterion, also uses label "rowcount"
