Title: Nicer rendering for trees

* use unicode box-drawing glyphs
* handle newlines in node labels somewhat intelligently
* one line per node

Example:
```
[error] │ └─ MapReduceTask
[error] │ ├─ ReadTask(zips2)
[error] │ ├─ JavaScript(function () {
[error] │ │ emit(this._id, {
[error] │ │ "left": [],
[error] │ │ "right": [this]
[error] │ │ });
[error] │ │ })
```
