(arm-2) Update ARM-2 Iteration to reflect implementation in Puppet 3.4
Update index for ARM-2 to show it is version 2.0.0

The ARM was updated with the changes for Puppet 3.4.
The public scrutiny and UX testing that has taken place since
the last publication should be enough for this to go straight to
versio 2.0.0.
Update ARM-2 after feedback on language.
Merge pull request #61 from hlindberg/master
