- changes to CHANGES

- The "-declarative" changes will now be listed
directly under the "-orm" section, as these
are closely related.

- The 0.5 series changes have been moved to
the file CHANGES_PRE_06 which replaces
CHANGES_PRE_05.

- The changelog for 0.6.7 and subsequent within
the 0.6 series is now listed only in the
CHANGES file within the 0.6 branch.
In the 0.7 CHANGES file all the
0.6 changes are listed inline within the 0.7
section in which they were also applied
(since all 0.6 changes are in 0.7 as well).
Changes that apply to an 0.6 version here
are noted as are if any differences in
implementation/behavior are present.
