Summary: Accessbility for tree control
New Features:
Bugs Fixed: LPP-7865
Technical Reviewer: max
QA Reviewer: (pending)
Doc Reviewer: (pending)
Documentation:
Release Notes:
Details:
- Made the root item childId=1. Padded the internal arrays so the
childId is the same as the array index.
- Negative childId seen (bug in reader?) Added some checks to ignore
them.
- Removed unused acc_* methods.
- When using sendAAEvent, must use the root object, not tree item
objects.

I made some other changes but backed them out. These compute and save
the depth and description for each tree item.
Tests:
Run test and see that changes to the tree control are voiced. Sometimes
the arrow keys don't change the tree control because the keys are
intercepted by JAWS. I found that running with lzt=html helps the output
and prevents the focus from moving to the devconsole. Sometimes the
application runs very slow because of JAWS.
Tree control works fine in swf9/dhtml
