I will add a small comment on naming:

IterableChangeBuilder build the description of an already applied change 
of a list.
We can, in the future, imagine adding a builder for the description of a 
runnable change on a list (by example for having a group of operations 
on a list triggering only one time the listeners: something like an 
atomic operation on the list).

These two changes (applied and runnable) do not have the same content 
needed and will probably have different builders.

I would suggest renaming IterableChangeBuilder to 
IterableChange*d*Builder (giving clean room for a future 
IterableChange*able*Builder).

My two cents (and one character).
