Server Chat Heads

To my surprise, the code mostly survived to the update!

Because of this I decided to do a bit of housekeeping and add some annoyances, fixes and I took the time to read the code ~50 times before realizing I am not handling an IO Exception that everyone dodged until a couple of weeks ago, whoops!
This fixes won't be backported until I figure out how to handle a Forgix project, once that's done this is going my first cross-version mod, with all the fixes applied on every version!

Changelog

• Ported the mod to 1.20.5
• Polymer AutoHost is now included with this mod (since you usually need it when using SCH, installing Polymer externally should overwrite the embedded version)
• Added a warning when Polymer AutoHost is not enabled (or Arte is not installed, if that's the case you are on your own since I don't have experience with that mod)
• Fixed and prevented a crash when Auth or Skin servers are not available
• Minor improvements (code cleanups, better logging, better error handling)
