multiple changes, see notes

- renamed drupalnode-template to simplenode-template to lower
  confusion (because there's also node-template which is used
  for more verbose node output like events)
- took another whack at fb social links (and failed again)
  it only seems to fire on document.ready, so obviously that's
  not going to work and I will need to take another approach
  (perhaps xfbml?) -- next commit will attempt this.
- minor comments cleanup (more will come after release, mostly
  just getting my fingers back into the code for now.)
