o New class of RSIStatItems introduced: items which keeps track of the user's usage. A global array keeps track of every second of usage or idleness in the last 24h. The new class is able to record parts of this array to calculate the percentage of usage in the last minute, hour or day (whatever interval <24h). At the moment only the activity of the last minute is added, as proof of concept. It should be possible to query more kinds of intervals.
o The statistic mapping uses pointers instead of direct instances of statistic items.
o One more krazy report fixed.
