v5.3 QoS and bug fix update

• Now can update vanilla and papermc servers, using their API to get direct download URL.
• Tweaked how server_log function works.
• Updated slime vars file, added, removed and moved stuff around.
• Added some time so Minecraft server receiving command has more time to log it before bot attempts to read log.
• Fixed imports. No more * imports (although imports lines still (I don't like multi-lined imports....))
• And probably a lot of other stuff I forgot, lmk if anything else breaks.
