* Fixed a bug where Tools.pm->_anvil_version() and Get->host_uuid() were storing values in the wrong $anvil hash.

Browse Source 
* Fixed a bug where Get->host_uuid() wasn't reading from the host.uuid file.
* Updated Remote->call() to record a target's fingerprint when needed.
* The ocf:alteeve:server resource agent now properly stopps a server and the corresponding DRBD resource.
