Add lichess.org outline as a style

[mliebelt]

Found the site lichess.org 2 months ago, and like it a lot. I would like to have the option to style the chessboard including notation as at lichess.org.

Here are some links to the analysis board of some games:

• http://en.lichess.org/U7V7PB7f#79
• http://en.lichess.org/hVIF9XUV#88

Especially the game when the computer analysis was done is interesting ...

The different possibilities are:

• Show notation inline (has to be set by the user, default is not).
• Show notation as list, with variations inline.
• Show notation a slist, with variations as list as well. Find a way to show that those are variations (additionally to the parenthesis used).

There are many examples on the internet, on different site:

• chess24.com: Uses notation as list, with variations inline. You can use that on any game, so every user has the option to create his own variations.
• chess.com: see an article there with the included games. Notation is inline, variations as well.
• chessable: notation is inline (only).
