Title: CHANGE collect system memory instead total

From erlang(3erl):

total = processes + system
processes = processes_used + ProcessesNotUsed
system = atom + binary + code + ets + OtherSystem
atom = atom_used + AtomNotUsed

RealTotal = processes + RealSystem
RealSystem = system + MissedSystem

Thus it makes more sense to collect system memory and sum `total` during
the display, if needed.
