Summary: Bring memory tracing to the modern era

Bugs Fixed:
LPP-5205: 'Debug.whyAlive no longer shows reference keeping object  
alive'

Technical Reviewer: philip at pbrdev.com (pending)
QA Reviewer: yfang at laszlosystems.com (pending)

Details:
     LzMessage: fix error in concat observed in passing, make
     appendInternal of another LzMessage concat, not present the
     message

     LzMemory: Make some things classes.  Stor leaks as a new class
     that has a pretty descriptor and breaks out the leak information
     for easy inspection.  Use a stable sort on leaks, sort the biggest
     leak to the front of the Array.  Make whyAlive describe the top
     leaks.

     LzDebug: Use user toString methods, obey unique flag.

     LzFormatter: New formatting flag `=` takes the next argument as
     the object to be represented by the format (overriding the normal
     hot-linking that occurs in the debugger so you can write a custom
     representation for an object).

Tests:
     Debug.markObjects()
     Debug.findNewObjects()
     Debug.whyAlive()

     now yields useful information:
