Added Guile Hoot, NerdLang, RingLang, and Wonkey

[vasilev]

Added NerdLang, RingLang, and Wonkey sections. Added Guile Hoot to Scheme section.

Reasoning

• Guile Hoot - declared as Guile->WebAssembly project. It's usable enough to build interactive web pages, and more.
• Nerd - declares WASM as supported platform. Has an JS-interop example. I've tested that example and it worked as expected. (But "compiler" itself needs to be patched to work on case-sensitive filesystem).
• Ring - declares WASM support and has list of WASM demos.
• Wonkey - has WASM as default compilation target. Uses Emscripten under the scenes. Has several demo games here.

This is a "Major additions" portion of #140 .
