[orca-list] Experimental Structural Navigation within SayAll committed to master

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

More experimental goodness has just been committed to master. Now, if
you use SayAll in Gecko or WebKitGtk, you should be able to use
structural navigation commands to go back and forward in order to
re-hear previously read content or skip over something you don't want to
hear. As with the new rewind and fast forward support, it's disabled by
default. To enable it, edit your orca-customizations.py file adding:

import orca.settings
orca.settings.structNavInSayAll = True

If you could beat on this, I'd really appreciate it.
