Currently a single ConversionService is used globally in a DispatcherServlet. It would be useful for controllers to be able to register converters and formatters locally for a given DataBinder instance without affecting the global ConversionService instance (for example ROO-1655).

Something along the lines of:
DataBinder.getFormatterRegistry().add(..)


Affects: 3.0.5

I'm introducing addCustomFormatter(Formatter formatter, String... fields) and addCustomFormatter(Formatter formatter, Class... fieldTypes) to DataBinder, internally adapting the given Formatter to a PropertyEditor and registering that adapter with the underlying PropertyEditorRegistry, following the usual rules there. This is a quite simple and straighforward approach which should hopefully cover the typical use case here, without having to build an extra local ConversionService underneath the covers.
