  Don't refresh observer table view if there was no change

OTP-12819

New info in 18.

Info available from erl-18 nodes.

Avoid refreshing the list of tables every refresh interval
(by default 10 secs) if the content did not change.
Because of the refresh the list was scrolled to the begining
and current selection was lost which could be quite anoying.

  observer: Fix menu code (for mac)
  observer: Add a new tab memory allocator charts

Have been broken since:
 6fe02e14d observer: Add SASL log view for processes

Easier to the see memory usage and utilization as charts instead of
values that is updating during runtime.

Remove from system page and create a separate allocator tab.
