Masco Skray 96d4a3ecf7 style(judger,web): move code out from subfolder "1"
Due to historical reasons, the code is in subfolder "1".
With SVN removal, we place the code back and remove the annoying "1" folder.

<p>Press <strong>ctrl-space</strong> to activate autocompletion. The
completion uses
the <a href="../doc/manual.html#addon_anyword-hint">anyword-hint.js</a>
module, which simply looks at nearby words in the buffer and completes
to those.</p>
