default LDM to CheckHostIP=no

i've thought for some time we should consider defaulting to ignore the host ip 
address, to reduce the need to run ltsp-update-sshkeys whenever the ip address 
changes.

security-wise, i'm not sure what we gain by erroring out whenever the ip 
address changes- as long as we're connecting to a known hostname and host key 
pair, the connection should be mighty secure.

alternately, could set it as default in the chroot's ssh_config options as part 
of ltsp-build-client.

thoughts?
