nettosphere-samples/jersey-chat gives wrong build instructions, and doesn't work

[lwahonen]

Readme.md says

`### Using the sample

bash % mvn % cd target % unzip nettosphere-jersey-chat.jar % chmod a+x ./bin/nettosphere.sh % ./bin/nettosphere.sh `

But the jar created by maven doesn't even have a /bin/ inside of it. Manually running org.nettosphere.samples.chat.NettosphereJerseyChat seems to work otherwise, but browsers pointed to 127.0.0.1:8080 cannot find atmosphere.js. Naturally, the chat functionality doesn't work either.
