Bump revision to 1.0.0 to move to Submitted state

No refinements have been made yet so I'm declaring this one-point-oh.
Bump ARM-1 metadata to 1.0 in preparation for Submitted state
Update index for ARM-0 and ARM-1 state / version / date
Merge branch 'master' of ssh://git@github.com/puppetlabs/armatures.git
Update README with status of updated arms.
