Help with #399 and #1237: Document built-in objects and add other language documentation


Now that we have a patch system and anyone can help add spell documentation from within the level editor, I wrote a guide for how to add documentation for various JS builtin types by looking at the Mozilla Developer Network documentation and excerpting it for CodeCombat:

#399: Help Document Object, Function, and other built-in objects

#1237: Add property documentation syntax for Python, CoffeeScript, Lua, Clojure, Io

Would really appreciate any help in getting all these builtins documented, and these other languages unleashed!
