Relax the method search algorithm used by `ReflectivePropertyAccessor`
to include methods of the form `getXY()` for properties of the form
`xy`.
Although the JavaBean specification indicates that a property `xy`
should use the accessors `getxY()` and `setxY()`, in practice many
developers choose to have an uppercase first character. The
`ReflectivePropertyAccessor` will now consider these style methods if
the traditional conventions fail to find a match.
