Large collections, like lists with thousands of items, either cause the debugger and the whole application to be very slow, or crash with a stack overflow. Closes elm/compiler#2133 Closes elm#90 Closes elm#104 Closes elm#132 Closes elm#120. That’s a previous PR that touched on this problem. That PR makes the experience go from crashing to awfully slow. This PR is fast even with big collections, by expanding just the first 100 items. There’s a “view more” button to show the next 100. I went with the simplest possible UX around that, since it’s unclear if anyone actually tries to click to item number 9000 – at that point, search is better. And then you could just as well do the search with Elm code and `Debug.log` rather than using some obscure search syntax in the debugger. I think looking at the model in the debugger is more for learning the overall structure of an app, than to look at every single item of long lists, sets or dicts.

This fixes issue #90.
I have tested it on the example given in that issue.
