like last time, this probably shouldn't be merged

Below is PR with simple bot stuff, you can go into src/apps/make-bot and run ./make-bot with following arguments:

• --id - name of the bot, because I'm a lazy engineer, this should be the same as name you give it in the makeBot() function below, this of course could be refactored/fixed
• --workspace - url for the workspace you're working on - I'm grabbing the current board url from navStack (obviously we could as well have --board but again, lazy)
• path to the javascript bot file

So for example:

./make-bot --id journaling --workspace capstone://Workspace/CvVAqKkXJiVPftFnoSC3tXAgZMy6jNyUDsmjFFZLLKir/FCh ./bots/journaling.js

I'm supplying two bots, one is fully autonomous -> ./bots/pinterest-organizer.js that will make sure your widgets are in pinterest-like state, and second one: ./bots/journaling.js which creates little widget, that can create time/date stamps on boards (as text widgets), so you can easily date stuff.

As for the bot API, here's what we have right now:

makeBot("bot id", bot => {
   bot.autonomous("Board", () => {
     // do something automatically every time anything on board changes
     //
     // first argument here is type of message sender to react to
   })

  bot.action("Organize", () => {
    // expose ui with "Organize" button that triggers 
    // the code in callback when clicked
    //
    // first argument here is name of action displayed in UI
  })
})
