Errors regarding EntitySpec.displayName

[Sam Corbett <sa...@cloudsoftcorp.com>]

Hi all,

A recent change to the class hierarchy around EntitySpec changed the 
location and the return type of the `displayName' method. If you run 
Brooklyn and observe errors like:

You need to recompile your project against the latest Brooklyn. The 
change was merged as part of pull request #106 
<https://github.com/apache/incubator-brooklyn/pull/106> on 7 August.
