python-console: Fix globals broken with new JSON library.

simplejson always returns unicode strings. cJSON would return ordinary strings 
if possible. cPickle.loads() only accepts strings. At present we use pickle 
version 0 so they should all works as ASCII strings. Higher versions of pickle 
are not plain ASCII and are likely to break this and so this should be fixed 
at some point.

Also replaced unconditional exception with one that catches Pickle errors. Not 
sure the best way to report failures of these functions.
