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.
