Can't pickle code objects

[GoogleCodeExporter]

I tried out the latest (97518ac8f0e0) version of ruffus and came across a 
problem with pickling of code objects.

Traceback (most recent call last):
  File "../../../pipelines/defuse_readthrough/defuse_readthrough_neuronal.py", line 548, in

There needs to be a (quiet) fallback path when pickling fails.

cPickle a function can fail, eg. for nested functions
Fixed: changes to checksum code to fall back to using marshal and then str() 
and then nothing
