The Atom's swap! function may run its provided function multiple
times. Because of this, using an Atom for the system state can
occasionally result in duplicate TCP connections being opened when the
system is started. These connections remain open until they
timeout (this is typically 5 minutes for IRC).
This commit changes the container for the system state from an Atom to a
Var, whose alter-var-root function (analogous to swap!) does not have
this issue.
