Make IndexPopulationFailures print properly resolved label name and property key ids
Update tooling git repo location.
Fix array storage corruption in batch inserter.

This addresses an issue where, when changing an array property from one array to another array of the same size,
the dynamic record storing the original value would get marked as not in use twice, putting it's id in the list
of reclaimed ids twice. That in turn would, obviously, allocate the same dynamic record twice to two different
properties.

Corrects DiffSets problems

There were problems in how the added/removed parts of DiffSets were
populated and managed in general. The problems were exposed in that
the 'remove' part contained invalid and/or too few entries and the
'added' part contained too many entries. In the property scenario
the diff set was used to remove the old property and add the new.
Add and remove were issued separated from each other, which made those
step on each others toes.

These things were changed:
o Introduced DiffSets#replace which does proper add/remove semantics
  knowing that one value replaces another.
o Removed null from the added/removed sets management by using empty sets
  in place of null. This makes for less checks, less code, more
  intuitive code and actually less objects being created since a set
  may not need to be created to remove something that it doesn't have.
o All *ArrayProperty (extends SafeProperty) classes have their value()
  method return a clone of the actual array. This fixes a problem with the
  initial test used to drive all these changes, where the test changed and
  reused an array property value read from a node.
o Safe equals() on LazyArrayProperty and clearly describes why the type
  member field needs no synchronization or volatility; both for
  readability and for reasoning about potential future changes to
  synchronization thereabout.
