updates to vector spec repo on github

Krste Asanovic

I added the change to add a vcsr including FP fields (this came out
much cleaner I think) - please check over.

Another minor change was to fold in the suggestion to move VS to a
two-bit wide gap lower down in *status to leave the higher wider field

I also bumped the draft date on the doc, and also added the meeting
minutes to the repo.
