Compiling for web

Dart apart from compiling to native code which was leveraged in the vscode extension, can also compile to javascript. The lang server can b compiled to javascript and interface with monaco-editor, the editor that powers vscode.

The entry point is in \bin\web.dart. Its interfaces with monaco-editor via service worker.
