FLUID-2936

[Alison Benjamin]

Hi,

This is a patch Colin and I have put together to address
http://issues.fluidproject.org/browse/FLUID-2936

This improves the indications a JAWS user will get about progress. It
doesn't solve the problem of the user needing an indication of when progress
is done. We suspect this problem lies with JAWS. Testing with another screen
reader like orca, which also has ARIA support, could help isolate the
issue...

Thanks,
Alison
