loading mask for repos
aggregated file metrics can be retrieved separately. values of complexity metrics based on incremental updates and delta data. revision info takes respect to currently selected package and file. filter tracks current package and file. metric ranges based on ranges submnitted by backend or max value. fixed bug where branch could not be switched in repo view.
reduced package names to important parts in filter package selector.
removed view call from instances and moved it to utils. structural metrics now also calculated using delta values. churn supports package filters. added some more insights for dev. how long did they participate. when did they start. are they currently active. how many revisions did the contribute per day on average. fixed a bug where revision info could not be shown if no package was selected.
