composite master renaming, and; multiple remote puts (rsync|scp)

* composite master files: eliminate ._sst, replace with .ssm.sst

* multiple remote hosts ("distributed" rsyncing), yml config files remote now
  uses array

with all recent changes (directory shunting) much testing is yet to be done,
state is unstable some things are known not to work this instant, e.g. sisu -V
