[patch] Incorrect SQL code in function casetracker_case_state_save

Issue Summary

function casetracker_case_state_save() executes invalid SQL code:

db_query("INSERT INTO {casetracker_case_states} SET case_state_name = '%s', case_state_realm = '%s'", $case_state['name'], $case_state['realm']);

I don't know if this is valid for mysql but this is not valid according to SQL standard.
