Bugfix & perf release.

  2.0.12 fixed the timeout code. But it had a nasty side-effect as the timeout
  setting is shared for global timeout and plugin timout. This version
  decouples both by introducing a new global_timeout munin-node.conf variable
  that defaults to 15 min.

This is a patched release, and I'll remove any .11 tgz as it's not-working.
