Log4J 1.2.17 Support

A handful of things to report this time around.

First and foremost I've widened the testing for both TimeAndSizeRollingAppender and ActiveAsynchronousAppender to include Log4J 1.2.17.  There are only a few changes in 1.2.17 and no changes were required to either the TimeAndSizeRollingAppender or ActiveAsynchronousAppender to be fully compatible.  The Maven 2 POM file dependency still shows up as 1.2.16, however this is a fairly arbitrary choice based upon improvements in threading behaviour in 1.2.16; there's no reason not to edit this for use with 1.2.15 or 1.2.17 if desired.

Secondly, the unit test coverage for the ActiveAsynchronousAppender has been increased considerably.  Some slight inconsistencies in the behaviour of classes targeted towards specific Java versions have been ironed out.

Finally, the www.simonsite.org.uk hosting has been moved.  A problem with IPS tag provisioning, caused by my original hosting provider, resulted in the site going offline for over a week.  This was highly regrettable and I apologise for any inconvenience this may have caused.  The site is back online after having completed the move to its new home.  New versions of the TimeAndSizeRollingAppender and ActiveAsynchronousAppender can be downloaded from www.simonsite.org.uk as before.

I hope the Appenders continue to be useful.
