- caching

- pie widget :)

- fix toplist widget

- timeseries-widget: cardinal on/off should be skeuomorph

- namespace picker in sidebar

- fix session view

- split up fnordmetric.namespace block into multiple files

- proper cmdline output (status?)

- pie widget (+ fix for old first)

- distgauge: render std. deviation

- timeseries-gauge: overview series weights

- timeseries-gauge: punchcards
