Add postBuild file so this works on mybinder.org about jupyter-shoebot

ok i added apt.txt and postBuild (to install the shoebot kernel into Jupyter) and the binder notebook is actually running!

however the shoebot kernel does not launch -- it's stuck at "Kernel starting, please wait..." and then disconnects from the server (the kernel runs fine in a local install)

there is one notebook that doesn't use the kernel (shoebot-as-python-module) which might be able to help pinpoint the cause. I'm stuck with this error on the line import shoebot:

/srv/conda/envs/notebook/lib/python3.7/site-packages/shoebot/core/__init__.py in <module>
     36 """
     37 
---> 38 from canvas import Canvas
     39 from cairo_canvas import CairoCanvas
     40 

ModuleNotFoundError: No module named 'canvas'

Also, when running that example locally, I get:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-2-55561089cd27> in <module>
      2 
      3 import shoebot
----> 4 import cairocffi as cairo
      5 from io import BytesIO
      6 from IPython.display import Image, SVG, display

ModuleNotFoundError: No module named 'cairocffi'

...which means that locally it can import shoebot but fails on cairocffi.

I'm a bit tired to go on for today. In any case, the problem might be that we're hitting binder's memory limits -- let's hope not :/

Done :)

Yeah, I saw this, but I could't make it work at http://myBinder.org, I don't know the incantations to set the environment!
I created the issue exactly because I saw this and thought it must be possible to do it.

I went through the Binder docs and think that the way to install the missing dependencies is through the apt.txt file. Trying it out now

Jeez just found out that Stuart did all this in this PR

I'll try it tonight, but wondering how it's working for you @stuaxo ?

Try the PR, for now it pulls in shoebot from GitHub.

Some bits get an exception in drawqueue but that's more that some changes in shoebot are needed.
