567	add version info to t=JSON output data	warner	freestorm	"It will probably make life easier in the future if we add a version number to the JSON output from operations like {{{deep-stats}}}, {{{deep-manifest}}}, and {{{deep-check}}}.

A related piece would be to tell developers that they should tolerate the presence or absence of each field.

On the other hand, the only customers of the t=JSON are:[[br]]
 1) The Tahoe CLI[[br]]
 2) Tools written to use the webapi functions[[BR]]

I'm ok with requiring that you use e.g. a 1.3.0 CLI with a 1.3.x backend instead of a 1.4.x backend, and developers have to play catchup all the time anyways. So I'm not sure how much energy I want to put into this.
