Add initial JSON formatter

It works and can format all "plain" Perl data, but has a few known bugs
and limitations that still need to be worked out.

It's about 8x smaller than JSON::XS's encoder and *much* smaller than
Cpanel::JSON::XS, but this is just a first attempt, it'll grow.

+## Project ideas
+
+Things that may or may not happen:
+
+- FU - The website framework, taking inspiration from TUWF.
+- FU::HTTPServer / FU::FastCGI - Minimal libs to support the web framework.
+- FU::JSON - JSON::{XS,PP,etc}-compatible wrapper around FU::Util's JSON functions? I prolly won't need this myself, but could be handy.
+- FU::Log - Basic logger.
+- FU::PG - PostgreSQL client with support for custom types and a small query builder.
+- FU::Util additions: `uri_escape`, `scrypt`, `urandom`.
+- FU::Validate - TUWF::Validate & normalization with some improvements.
+- FU::XML - TUWF::XMLXS with some improvements.
