Fold method chaining

[swekaj]

Add an option for folding method chains. The foldtext should display the chain as if it's on one line.

function let(Config $config)
{
    $config
        ->get('.buildable')
        ->willReturn('value');
}

Should fold into

function let(Config $config)
{
 +--- 3 lines: $config->get(...)->willReturn(...)-----------------------------
}

Did some investigation on this. While the example given would be quite easy to fold, something like

function let(Config $config)
{
    $config
        ->get('.buildbale')
        ->willReturn([
            'value1',
            'value2'
        ]);
}

is a lot harder to handle. It's very difficult to figure out that the ]); line not only closes the fold created by the opening '([' line, but also the fold created by the $config line.
