Should refer to latest esgf-node-manager jar when building.

	all modules compiled for me, except for the last one (esg-desktop):

[ivy:resolve] 	==== spring-external: tried

I think this could be easily solved by changing ivy.xml to:

<dependency org="org.esgf" name="esgf-node-manager" rev="latest.milestone”/>
