Unable to pass attributes to Client constructor

[trburgess]

The client supports an array of attributes as a second argument to the constructor:

        if (isset($attributes['channel'])) {
            $this->setDefaultChannel($attributes['channel']);
        }
        if (isset($attributes['username'])) {
            $this->setDefaultUsername($attributes['username']);
        }
        if (isset($attributes['icon'])) {
            $this->setDefaultIcon($attributes['icon']);
        }
        if (isset($attributes['link_names'])) {
            $this->setLinkNames($attributes['link_names']);
        }
        if (isset($attributes['unfurl_links'])) {
            $this->setUnfurlLinks($attributes['unfurl_links']);
        }
        if (isset($attributes['unfurl_media'])) {
            $this->setUnfurlMedia($attributes['unfurl_media']);
        }
        if (isset($attributes['allow_markdown'])) {
            $this->setAllowMarkdown($attributes['allow_markdown']);
        }
        if (isset($attributes['markdown_in_attachments'])) {
            $this->setMarkdownInAttachments($attributes['markdown_in_attachments']);
        }

It would be great to be able to define them in the config and then have that passed to the constructor.

I would be happy to submit a PR for this.
