Change behavior of /project list command

[tannerwelsh]

Based on LearnersGuild/echo#431, /project list -r will no longer be used.

The -r flag is to be removed, and /project list will display all active projects, the handles of their team, and the artifact url.

Example usage

@learner  > /project list
@echo     > There are 5 active projects.

            #terrible-tiger
            @billy, @bobby, @bud
            https://github.com/owner/repo

            #anxious-aardvark    
            @sally, @sarah, @sid
            https://github.com/owner/repo

            #silly-slug          
            @timmy, @tommy, @ted
            https://github.com/owner/repo

            #fantastic-falcon    
            @gabby, @gilly, @gaz
            https://github.com/owner/repo

            #creepy-caterpillar

@tannerwelsh this looks great, although I think displaying team members inline like you suggest is going to cause very awkward formatting, since sometimes teams are as many as 5 people and handles are as long as 13-14 characters. It's going to make it really hard to read, and the columns won't line up.

[tannerwelsh]

Good point @jeffreywescott. Just changed the output to make the project data multi-row instead of multi-column. Should reduce the total width of output, and make it more readable.

Omitting labels because the formatting of each line provides needed context to understand what it refers to (e.g. # for project name), and having a black line between projects creates an unambiguous separation.

Admin UI to the rescue!
