BrowseResultMask includes "odd" enum values

[jouniaro]

public enum BrowseResultMask implements Enumeration {

    None(0),
    ReferenceTypeId(1),
    IsForward(2),
    NodeClass(4),
    BrowseName(8),
    DisplayName(16),
    TypeDefinition(32),
    All(63),
    ReferenceTypeInfo(3),
    TargetInfo(60);

The last 3 values are bit sets, instead of enum values and don't belong there. Also None is useless. We have constants for the sets already and could define the other sets similar ways:

	public static EnumSet<BrowseResultMask> NONE = EnumSet.noneOf( BrowseResultMask.class );
	public static EnumSet<BrowseResultMask> ALL = EnumSet.allOf( BrowseResultMask.class );

The problem is that these are generated from the UA Defined Types.xml, which is defining the bit sets as well, so they should be removed from there in practice.
