FYI: New DataFlavor tests

[Roman Kennke <roman dot kennke at aicas dot com>]

This adds two tests for DataFlavor.readExternal() and
DataFlavor.writeExternal().

2006-10-30  Roman Kennke <kennke@aicas.com>

	* gnu/testlet/java/awt/datatransfer/DataFlavor/readExternal.java,
	* gnu/testlet/java/awt/datatransfer/DataFlavor/writeExternal.java:
	New tests.
