Object pretty-print

[towergame]

Set up pretty-printing for objects, perhaps even syntax highlighting

TODO list:

• Switch the logging functions from string to any
• Add the ability to make it log as JSON (or anything else, if there's a better way of doing it)
  • potentially add a special case for if the output is a browser console, as they handle objects themselves
• On ANSI-supported consoles, add syntax highlighting

[towergame]

Still need to figure out what to do in the case of browsers (as of right now, there is no detection whether or not its logging to a browser), but otherwise the feature is complete.
