Allow direct inspection of EAR files

[GoogleCodeExporter]

As a developer of applications that use the "enterprise archive" (EAR)
format, I would like to be able to scan such files by including them on the
classpath as follows:

 $ testability-explorer.sh com.acme -cp my-app-1.0.ear

An EAR file is simply a ZIP-format file that contains one or more other
ZIP-format files in its top-level folder, see
http://en.wikipedia.org/wiki/EAR_%28file_format%29.

With the tool as it currently stands, I have to unpack the EAR file
manually and add each individual archive (JAR, WAR, etc.) to the classpath.
