Support for MatterMost (A slack alternative)?

[hcorion]

Hi dev(s),
Awesome to see this plugin open source!
Slack however is not open source, and I have found Mattermost, which is an open source slack alternative. The Mattermost website says that

Mattermost is “Slack-compatible, not Slack-limited”, supporting a superset of Slack’s incoming and outgoing webhook integrations, including compatibility with existing Slack integrations.
Would this mean that by Mattermost would be compatible with this plugin? I can try and do some testing to test compatibility with Mattermost. I have a fair bit of programming skills (Java is my greatest though) so if there is some work to be done to support Mattermost, I would be willing to look into it.

Have you tried just setting the URL to a Mattermost incoming webhook? It sounds like nothing is needed for us to do to support it.

I actually haven't setup a Mattermost server. I will get back to you on that.
