The goal of this is to keep track of what app processes are doing, to determine who is being abusive, when the system is getting into memory constrained situations, and help the user determine how to resolve this. Right now it doesn't really do any of that, just keeps track of how long every process has been running since boot. Also update the activity manager to use "cached" as the terminology for what it used to interchangeably call hidden and background processes, and switch ProcessMap over to using ArrayMap.
