names the lastsynced file to include the both the machine name and appdomainappid. allows {appdomainappid} to exist as a token in the examine index path. adds some error checking to the examine mgmt controller if it cannot read the details. adds a couple of public readonly properties to the base examine indexer so these details show up in the examine mgmt dashboard. updates all config files to work with shared storage on a single machine, of course we should not ship with these settings but i wanted to commit the changes for a reference.
