Security audit progress and outcomes

Hi,

Are there any security audit findings for Mattermost that can be published?

A couple of blog posts refer to a MM security audit:
- This post announcing the tie-in with Gitlab, which says Gitlab will fund an external audit.
- The 1.0 release announcement says MM has passed a security audit, but the reference doesn't provide any audit findings.

For context, we're doing a bake-off between Mattermost and Hipchat, and any evidence or findings from a security audit would be very helpful in making the case for Mattermost.

Thanks,
Blake
