We now store teh sessionID of the gateway connection for later use. We
are now caching the gateway url and will use it until unable to connect
to that gateway. We're not longer smashing the VoiceConnections map
during reconnects which was causing Voice problems. Slight change to
log output format.
Corrected the Event struct to match it's new state based on Discord docs
and started tracking sequence number and sending it with heatbeats.
Also, move cleanup and comment improvements.
This adds a LogLevel setting for both Websocket and VoiceConnections
that can be configured to set the specific log level desired. This
also adds a new logging function that adds additional helpful
information when printing out log messages.
