[morph-developer] changes

[Matt B. <gud...@ya...>]

IMHO this is sort of big:  it yields a speed
improvement in the test cases, and I feel it serves a
practical purpose as well.  Anyway, I wanted to call
attention to it so that it could be shot down if need
be.

I have modified BaseReflector NOT to set properties to
identical or immutable-and-equals() values.  This is
especially important with copiers, because when you do
deep copying, you often don't really need to set the
value because you've only changed the state, if you
will, of the same actual object instance.  Where this
really helps, however, is in the situation where you
are copying to objects with getters but no setters. 
Because the actual value object is the same, Morph
will now recognize that there is no need to perform
the set() and thus its functionality should be
extended as a result of these changes (it won't fail
trying to perform sets it didn't have to do to begin
with).

These are revs 101 + 102.

-Matt
