Handle new/old nREPL stacktraces - fixes #258

Browse Source 
At some point there was an upstream change to the message format that
cider-nrepl returned. This resulted in in a crash when trying to eval
an expression that threw an exception, resulting in the exception
being obscured by a Vim error, and no stacktrace being produced.
This patch inspects the returned payload and optionally extracts
any embedded stacktrace before processing.
