Change the structure of the iPOJO project.
Handlers are now in a separate directory (handler).
Update the iPOJO pom file to refer on the moved projects.
Update some artifactId to be consistent.

+ * This is a very simple bundle tracker utility class that tracks active

+ * opened to track objects and closed when it is no longer needed. This
+ * class is abstract, which means in order to use it you must create a
+ * subclass of it. Subclasses must implement the <tt>addedBundle()</tt>
+ * and <tt>removedBundle()</tt> methods, which can be used to perform some
+ * custom action upon the activation or deactivation of bundles. Since this
+ * tracker is quite simple, its concurrency control approach is also
+ * simplistic. This means that subclasses should take great care to ensure
+ * that their <tt>addedBundle()</tt> and <tt>removedBundle()</tt> methods
+ * are very simple and do not do anything to change the state of any bundles.
