Merge #917

917: Trait tests r=flodiebold a=flodiebold

This adds a bunch of basic tests for trait functionality, just to outline what seems like the first goals for that ;)

It also changes the display of `Ty::Unknown` to `{unknown}`, since `[unknown]` could be confused with a slice, and fixes an error in the emacs runnables code.
