Reschedule the timer event after processing timers. Fixes #458.

If the libevent timer fired too early, this would cause all timers to hang until some timer was rescheduled. With this change, the timer event will be rescheduled to fire just after the first timer expires and thus always keep the timer processing going.
Avoid premature timer events in the libevent driver if possible.
Silence some debug messages.
Fix Libevent2Driver.resolveHost for names that can be resolved immediately.
Fixed RedisClient.zcount.

Note: I did not actually test ZCOUNT because I ended up not
going for Redis in my current project, but this caught my
eye while perusing the implementation.
Provide explicit Bson.toString() method.

Otherwise, opDispatch() will be invoked when trying to
writeln() a Bson object for debugging purposes, leading to
a confusing exception.

I'm not sure whether goign through Json is the best idea,
it just seemed like a convenient fix for the time being.
