Do not want excerpt to auto-generate if empty

[simonrjones]

Currently {{ page.excerpt }} returns the first line of content if it is empty in WordPress. This is not desired on the template Sean is working on.

Ideally this would behave like so:

• Output the actual content that exists (even if empty)
• Give the user the option to auto-generate but do not make this default

    public function getExcerpt(int $limit = 200): string
    {
        if (empty($this->excerpt)) {
            return $this->trimContent($this->__toString(), $limit);
        }

        return $this->excerpt;
    }

One solution, which does break backward compatibility:

    public function getExcerpt(bool $generate = false, int $limit = 200): string
    {
        if (empty($this->excerpt) && $generate) {
            return $this->trimContent($this->__toString(), $limit);
        }

        return $this->excerpt;
    }
