UI: experimentation view: one node output window for the output of all nodes

[danbim]

Create a widget that can be ideally used without WiseUI that is able to connect itself to a running experiment and provide the outputs of all or individual sensor nodes. The user should be able to select a subset of nodes, the type of message interpretation (as String, hexadecimal, octal, decimal, provide format Strings) and to download the resulting view of the experiment output.
