Add comparison to UCL - universal configuration language as well about arp242.net

UCL:

• The "automatic array creation" of UCL/nginx sounds like a recipe for an unexpected attack vector at worst... and an unexpected crash at best.
• The benchmarking is a bit disengenous... since JSON is a subset of UCL, it's simply not possible for it to be faster in a fair test. "nearly the same", i'll buy. It makes me trust the rest of the site less.
• Macros can result in the billion-lol attack, and includes, also are unsafe, so it's important to note that UCL is for "trusted sources only"
• UCL's macros and includes can be good for expressing a series of complex config files... but at that point, you might as well express it with eval().... it's just as secure and probably more powerful

By contrast:

• TOML is a very decent config file spec.
• Safer than UCL and is more readable than JSON.
• For configuration... it follows the INI-file syntax, which is well-known.
• Some smart things in TOML:
  • bare keys are always strings... unlike YAML where they can magically be anything
  • multiple keys are not allowed (JSON bad)
  • nesting is simple, good support for multiline strings, bools only have 2 values, date support,
  • comments

In my (random person on the internet) opinion.

Thanks for the suggestion @igor84, as well as @earonesty for your thoughts.

I removed the entire Alternatives section for now, as I don't have the time or interest to do a comprehensive and fair review. See #8 (comment) for a more detailed rationale.
