Revert #82 and #79

[mickmister]

Summary

Reverts the following PRs due to having incomplete functionality:

• [mm-65] Allows users to add multiple teams to the messages using team-a,team-b in the messages #82
• solves Gh 72 - Welcome bot will not let me add a message to private channels #79

I've also reopened the tickets associated with those PRs:

• Allow same welcomebot message for a number of MM Teams on same server without repeating message text #65
• Welcome bot will not let me add a message to private channels #72

Is the missing functionality written anywhere? Can't that be completed without reverting the code?

Thanks @mickmister I see this working as expected for the reverts.

As we are making a last set of changes here, Can you please add something to the read-me that covers an example of using the new guest-account support feature?
It would be helpful if you could just add that middle line below to the read-me as you already have changes in.

                        "DelayInSeconds": 3,
                        "IncludeGuests": false,
                        "Message": [

@DHaussermann I'm inclined to do this in a separate PR as it's out of scope of reverting these two PRs. Thoughts on merging this PR as-is?

Tested and passed as per comment above.

Read M edit will be addressed separately.

LGTM!
