Generate the table of contents dynamically from $Content.

This is basically a SilverStripe 3 module that extends the ContentController class to provide:

• the new $Autotoc tag, containing the table of contents dynamically created from the content of the current page. The tree is provided as a mixture of ArrayData and ArrayList, ready to be consumed by templates.
• overriding of the standard $Content tag, augmenting it with anchors (<a> elements with the id attribute but without href) that adds proper destination targets to the links in $Autotoc.

The $Autotoc is a tree that can be represented with the following pseudo representation:

$Autotoc = ArrayData( $Children <- <CHILDREN> )
<CHILDREN> = ArrayList( <ITEM> )
<ITEM> = ArrayData( $Id, $Title [, $Children <- <CHILDREN> ] )

In a more SilverStripe template way, this can be seen as:

$Autotoc
    $Children[]
        $Id
        $Title
        $Children[]

The Autotoc.ss and AutotocItem.ss shows a way to represent the whole table of content tree in a recursive way. The format used is intentionally compatible with the Bootstrap navlist components, so it can be used and it will be properly handled by the Silverstrap theme.
