Exception information not available when breaking on 'Raised Exceptions'

[DonJayamanne]

The exception information (name, type) is not available when breaking on exceptions.
Exception message needs to be returned in the text property of the stopped event.

See here:

Is this a new issue or regression?

I came across this last week, but assumed it was caused by #117.
After further research I've learnt that not to be the case, as mentioned above, text needs to be returned. However getting this exception information is no trivial task.

From what I can see following methods aren't being invoked (for unhandled exceptions). I guess you already know this.

    @pydevd_events.handler(pydevd_comm.CMD_SEND_CURR_EXCEPTION_TRACE)
    def on_pydevd_send_curr_exception_trace(self, seq, args):

    @pydevd_events.handler(pydevd_comm.CMD_SEND_CURR_EXCEPTION_TRACE_PROCEEDED)

Expected behavior: (modified PTVSD, but does not work for unhandled exceptions).
