Version 2.0.0 beta - Test Candidate 8

The major changes in this release is much improved support when running Install Manifest against a good node and a rebuilt/replaced node. Now, InstallManifest will effectively mark a node that is hosting one of more servers as 'read-only'. The only change that will be make to that node will be the update of the peer's SSH details. Also updated to better reconfigure Striker's virt-manager (and backing SSH stuff) to handle a replacement node without user interaction.

NOTE: Supersedes the now-deleted tc7 which had a compile-time error in it.
