Title: New visualization for brew reps --tree

I suppose it would break parsers, but for me it's easier to visualize the deps tree with this new style.
```
$brew deps mapnik --tree
mapnik
|- pkg-config
|- libtool
|- libtiff
|- proj
|- icu4c
|- jpeg
|- boost
|- gdal
| |- jpeg
| |- giflib
| |- libtiff
| |- libgeotiff
| | |- libtiff
| | |- lzlib
| | |- jpeg
| | |- proj
| |- proj
| |- geos
| |- sqlite
| | |- readline
| |- freexl
| |- libspatialite
| | |- proj
| | |- geos
| | |- sqlite
| | | |- readline
| | |- freexl
|- geos
|- cairo
| |- pixman
| | |- pkg-config
| |- pkg-config
| |- xz
| |- glib
| | |- pkg-config
