Subject: [PATCH] Fix memory leak by holding on to Emoji references weakly.

The library had a memory leak in the case using the global emoji cache.
When the bot would leave the guild, the Emoji would maintain a strong
reference to the Guild keeping them alive along with the entire state
associated with it.
