Fix block on spawning multiple shards

When spawning multiple shards (via an equal number of futures - one
per shard) joined on a core.run use, the very first future executed
would block forever due to a sync, blocking `monitor_shard` use. While
this defeats the purpose of tokio, this was meant to be a first step to
an async serenity implementation.

To "fix" this blocking call until a deeper async implementation is made,
spawn a new thread per tokio core (and thus per shard). This causes the
same expected behaviour, just with multiple threads like before.
