Convert global channel operator support to OFTC's God mode.

OFTC's God mode is very similar to the global channel operator mode,
with the following differences:
- gaining God mode notifies all operators
- uses of God mode privileges notifies all operators
- God mode times out after a configurable period
- uses umode S rather than O - S is taken for SSL clients in
  hybrid 8.1.13.

So align with OFTC's implementation, but omit these features.
