A lot of bugfixes

I fixed a lot of bugs with the bot causing unnecessary errors and other unintended things. Some of these include:

Retrying failed requests (this fixes the images sometimes not generating because somehow once in a while the first request to mcheads fails.)
Add better error handling for players. (fixes the message that should happen when trying to fetch a player that does not exist (Wifies reference!!?? /s) )
Now register font separately from command for more performance
Fix some errors in logging
