/** Container for a single chat message composed of multiple functional parts.
Each part corresponds roughly to the behavior supported by the client messaging:
	- plain text, optionaly colorized / styled
	- clickable URLs
	- clickable commands (run)
	- clickable commands (suggest)
Each part has a text assigned to it that can be styled. The style is specified using a string,
each character / character combination in the string specifies the style to use:
	- b = bold
	- i = italic
	- u = underlined
	- s = strikethrough
	- o = obfuscated
	- @X = color X (X is 0 - 9 or a - f, same as dye meta
If the protocol version doesn't support all the features, it degrades gracefully.
