Add customizable alt text for images (#144)

[ssciolla]

The PR aims to resolve #144. (Plasmic changes have already been made.)

Tested this out and looks good

One suggestion is to make this change to admin.py

Then the image and the alt text are on the same line in the admin UI

Easiest way I could see to do it.

I saw an app for adding alt text to any FileField and what we have seems simple enough for now since we've just got the 2 images.

Sure, done, that seems like a nice change. https://github.com/tl-its-umich-edu/canvas-app-explorer/pull/151/commits/9e9c4317e767684d0343a18f352c5d4d2e26c8b8

Not totally convinced by the library, but maybe I'd have to try it out. Maybe if application was more about images, or we used template tags. It did occur to me that the data modeling is clunky (alt text and image path could be part of an image model, which could then be related to LtiTool M:1), but that's probably unnecessary, right?

Gonna merge for now, thanks for the review.
