Manual for the Web Lua REPL

This web app has a few caveats to its use that normal Lua does not suffer. For the Lua documentation, please view the Lua Read Me (Cached).

1. Files only persist if written to the /idbfs/ folder.
2. Changes to persistent files are only written from the Lua REPL if you press the Persist File Changes button.
3. dynamic library calls currently do not work, although it is possible to eventually support such things by allowing .wasm and .js files to be uploaded.
