Make Description required, fix typo (Reportal --> Report), clean up .classpath

In .classpath, if you add the src classpathentries, Eclipse complains with all sorts of errors.  Do we want to leave those in?  Also, why are some libs pulled from plugins/*/lib and others from dist/*/packages/*/lib?  I'm not sure about all my changes, but I fixed some of the paths based on the `ant` output and the new versions of the libs.
