j8583 1.2 for Java 1.4 and 5 available

I have release version 1.2 of the j8583 framework. The new stuff is mainly java.nio (there's a new example Server class that uses channels for network connections and the IsoMessage class can now create a ByteBuffer with its encoded message).
Also, there is a Java 1.4 compatible version of the library; it is highly recommended that you get the source directly from the SVN repository and build with the included ant file.
