Updated to use new KenyaUI app-based security system
* All controllers annotated with @AppPage, @SharedPage, @PublicPage (except html form related pages... WIP)
* Removed all references to AppUiUtils which is due to deprecated
Replaced KenyaEmrUiUtils.simpleXX methods with spring converters
* Updated test UI classes to use TestUiUtils instance with working conversion service
Converted most KenyaEmrUiUtils.simpleXX methods to converters so that we can invoke that functionality via ui.simplifyObject etc
