CRM-15454 - Enable multiple WordPress plugins to receive callbacks from CiviCRM hooks
CRM-15431 - CRM_Core_I18n - Use CRM_Core_DAO::escapeString for typical, runtime escaping

The call from CRM_Core_I18n breaks on systems that use "mysqli" without
"mysql." Such systems cannot be fully supported for development using
current dataflows (i.e.  "GenCode" won't work), but this patch may make them
usable for regular installations.
Log fatal errors for AJAX responses. CRM-15560

If you have a fatal error in an AJAX call, then the error doesn't get

happens after the call to CRM_Core_Page_AJAX::returnJsonResponse in
CRM_Core_Error::fatal and returnJsonRespons exits php.
