[Accessibility-ia2] Non-doc changes since IA2 1.0

[Pete Brunet]

Since there is an interest in re-harmonizing IA2 and ATK here are the
non-doc changes since the 1.0 release.  As far as I remember, changes
since 1.0.1 have not been harmonized with ATK.  This information came
from the changes logs, e.g.
http://accessibility.linuxfoundation.org/a11yspecs/ia2/archive/ia2-1.1/changelog.txt 
You can find all the change logs by starting at
