This checkin enables the StartDocumentLoadEvent. Now adding the rest of

the DocumentLoadListener events will be trivial.

Next step: flesh out the rest of the DocumentLoadListener events.
Modify NavigationTest so that it does its selection checking inside the
listeners.  This will probably require creating a Thread, managed by
EventRegistrationImpl, that is used to process callbacks from mozilla
into Java, so that we don't get deadlock.

M classes_spec/org/mozilla/webclient/impl/wrapper_native/EventRegistrationImpl.java

- remove all dependencies on NativeEventThread

- introduce dependency on BrowserControlCanvas (needed for future
  MouseListener) work.

- {add,remove}DocumentLoadListener() now just a matter of
  adding/removing to List.

- add nativeEventOccurred() method, called from native code

M classes_spec/org/mozilla/webclient/impl/wrapper_native/NativeEventThread.java

- remove dependency on BrowserControlCanvas

- removed nativeEventOccurred

M src_moz/EmbedProgress.cpp

- delete the global ref in the dtor.

- create the global ref in SetEventRegistration().

- call back to Java on startDocumentLoad.

M src_moz/NativeBrowserControl.cpp

- initialize our string constants.

M src_share/jni_util.cpp
M src_share/jni_util.h

- alter the signature of util_SendEventToJava

-void util_SendEventToJava(JNIEnv *yourEnv, jobject nativeEventThread,
-                          jobject webclientEventListener,
+void util_SendEventToJava(JNIEnv *yourEnv, jobject eventRegistrationImpl,
                           jstring eventListenerClassName,
                           jlong eventType, jobject eventData)

M test/automated/src/classes/org/mozilla/webclient/NavigationTest.java

- show that the DocumentLoadListener gets called.
