maven repository directory changed

[Art Allisany]

In the quick start tutorial:

http://ant.apache.org/ivy/history/trunk/tutorial.html
it says to cd to:

src/example/hello-ivy

but it doesn't work because the maven repository reorganized their 
directory structure.

so the src/example/hello-ivy/ivy.xml in the download bundle is

<ivy-module version="1.0">
    <info organisation="apache" module="hello-ivy"/>
    <dependencies>
        <dependency org="apache" name="commons-lang" rev="2.1"/>
    </dependencies>
</ivy-module>

but should be

<ivy-module version="1.0">
    <info organisation="apache" module="hello-ivy"/>
    <dependencies>
        <dependency org="commons-lang" name="commons-lang" rev="2.1"/>
    </dependencies>
</ivy-module>

after this change the tutorial will work.
