Enhance UI (#1243)

* Temporarily disable data file writing as it can cause crashs, see https://github.com/jomjol/AI-on-the-edge-device/issues/1225

* removed edit function in graph as we don't need that in a release

* .

* improve log viewer

* replaced logfile enable/disable with enum to select log level. At least errors always will be logged (as before)

* .

* .

* colorize log

* scroll down

* improve log reload
