Should really be mixing two fixes in the same commit but that's the way it goes

+ * Test case provided #41 Fix for SafeArray(String) constructor
+ * 
+ * In the current release of Jacob, SafeArray.java contains a constructor which
+ * takes a string as a single argument. The documentation claims that this
+ * method converts a string to a VT_UI1 array. Using this method as written
+ * always causes a ComFailException, because it attempts to create a SafeArray
+ * from Java chars, which are 16-bit unsigned integers (which would be VT_UI2).
