This checkin is the first step to making DocumentLoadListener work

again.  It provides the native class that implements
nsIWebProgressListener, which I've copied form gtk_moz_embed, so it's
gotta be good.  The next step will be to hook this up to the java side.

A src_moz/EmbedProgress.h
A src_moz/EmbedProgress.cpp

- mostly copied from GTKMOZEMBED

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

- remove javadoc reference to non-existing method

M src_moz/EmbedWindow.cpp
M src_moz/EmbedWindow.h

- expose AddWebBrowserListener method.

M src_moz/InputStreamShim.cpp

- make FileInputStream testcase run

M src_moz/Makefile.in
M src_moz/NativeBrowserControl.cpp
M src_moz/NativeBrowserControl.h

- add EmbedProgress

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

- Make this test run
