* EA-171 - Changed GP_LAST_VIEWED_PATIENT_SIZE_LIMIT validation to be done inside getDefaultLocale
(The validation is now done every time the function is called)
* EA-171 - Reverse removal of limit validation
Although processMessage is called during Openmrs start, and getLastViewedPatientSizeLimit already validate the limit, this function is also called every time a new recentPatient is added, so indeed limit is required
* EA-171 - Change from using commons logging to the slf4j facade
