add cpu/memory usage, uptime to nodeview

this patch adds a custom progressbar widget  which changes color,
depending on the value, and adds cpu/memory usage and uptime as columns
to the nodeview
altough those columns are missing in the model/api call, this works , because we
inject the data in our data collectin loop and having the fields not in
the model, causes the store not to overwrite them
