[Haskell] ANNOUNCE: SourceGraph-0.6.0.1

[Ivan Lazar Miljenovic]

I realised soon after I sent the announcement email that there was a bug
in one of the new "subtle" features that I didn't list, namely the
background shading of directories in import visualisation.  As such,
SourceGraph 0.6.0.1 contains this fix.

There were also two other features in 0.6.0.0 that I forgot to mention:

* SourceGraph will (well, should; I haven't managed to come across a
  situation where it occurs anyway) no longer throw a fit if Graphviz
  throws an error when visualising a graph; instead it will just put an
  error message into the generated report.

* The generated Dot code is also saved in the SourceGraph/graphs/
  subdirectory, so you can tweak the call graphs of your programs.

> * Now supports "implicitly exported" entities (as requested by Curt

>
> * Edges are now colour-coded based upon whether they are part of a
>   clique, cycle or a chain.
>
> * Level-based analyses: visualise how deep an entity is from those
>   exported entities.
>
> * A re-done TODO that lists in detail what is planned for SourceGraph.
>
> * Lots of under-the-hood changes that don't sound as interesting as the
>   above :-(
