updated at-spi 2 packages in Natty

[Alex Midence]

Hi, all,

I wanted to know if there were any plans to get a more up to date
version of at-spi 2 working in Natty?  It's still using 2.0.2 or
something like that and at-spi2 is at 2.2.0 if not 2.2.1 by now.  I've
seen quite a few at-spi update messages in the last few months
containing all sorts of fixes and things from upstream but nothing
seems to have changed in the ppa for Ubuntu.  There a reason for this?
