Accessible Spinners

[Steven Githens]

Hi Fluid,

I was looking at the Progress Component, and it clearly states that it 
should be used for linear things with a known time.

Are there plans for an accessible spinner, or making the progress 
component more generic to be used for events with an unknown time as well?

In lieue of that, what is the best way to do a spinner at the moment?  A 
custom jQuery UI dialog maybe?  Also thinking about if you only want a 
portion of the page to be spinnered off (like you may want the top menus 
to still work).

Cheers,
Steve
