This commit uses the new parameter with_status from nedap/pypuppetdb#18
Node status is now shown as text with the additional information of
failed/succeded events, unreported time
The statistics on Overview now show the *number of nodes*
that have status failed/changed/unreported
- the amount of hours is defined as `UNRESPONSIVE_HOURS` in default_settings.py
- small status layout improvement in nodes list
- latest report button in nodes list
- nedap/pypuppetdb repo as requirement ( new api was merged nedap/pypuppetdb#17 )
The following frontend features are implemented
- Number of failures, successes, noops/skips in overview
- Show latest reports with 1 or more events in overview
- Direct links to latest Report
- Number and types of events in nodes list
