đź“‚Folders to organize diagrams

We now have folders!

Building on the recent revamp of the dashboard, we've added folders as a way to logically group related diagrams.  This was actually the first-ever suggestion received when our suggestion board was launch exactly a year ago! Pretty stoked to have this shipped, should be useful with the growing number of diagrams for each team.

Of course, you can easily move a diagram between folders too. If you've started using folders, let me know what you think!
