	* convert.cs: Use `TypeManager.IsValueType' instead of
	'type.IsValueType' everywhere.

	* typemanager.cs (TypeManager.IsValueType): Return true for type
	parameters.  The reason for this is that we need to box a type
	parameter when converting it to a reference type.

	* cs-parser.jay: Added support for default value expressions.

	* generics.cs (DefaultValueExpression): New public class.
