Title: Simple GraphViz export

A very crude export mechanism to graphviz file format.

Supports taps (with explicit module name, even if first position)

Does not support other channels

Also note that some complex setups seem to break dot (but file opens up correctly in OmniGraffle)

Example rendering:
```
Stream Name Stream Definition Status
----------- -------------------------------- --------
bar http --port=9898 | filter | file deployed
fiz tap:bar.http > hdfs
fiz2 tap:bar.filter > splunk
foo http | log deployed
```
