Add support for KeyboardInterrupt in REPL

[YashSinha1996]

On keyboard interrupt in REPL, it raises the following stacktrace:

Error in sys.excepthook:
Traceback (most recent call last):

    "a frame or a thread object." % repr(thing))
ValueError: Can't format (<class 'KeyboardInterrupt'>, KeyboardInterrupt(), None). Expected an exception instance, sys.exc_info() tuple,a frame or a thread object.

Original exception was:
KeyboardInterrupt

I would love to contribute to help out, but I am not sure what the behaviour should be in this case?

Awesome project BTW.

Thanks! Can you post your python version? I can't reproduce it on 3.5.2. Though I get a similar problem on syntax errors in the REPL and might have an idea to fix both. Looks like the traceback is None for that exception, which should be easy to deal with (= just print the exception)

Hey @cknd I am on 3.7.2.

This should be fixed on the latest release (0.2.0). Can you do a pip install -U stackprinter to confirm?

[YashSinha1996]

Hey @cknd thanks a lot. Fixed!
