Title: Raise an error on unknown Bitcoin private key

Without this, when an invalid private key is entered, we get this exception:

> Traceback (most recent call last):
File "convert.py", line 91, in
print(numtowif(wiftonum(args.key)))
File "convert.py", line 61, in numtowif
step1 = chr(args.version)+numpriv
AttributeError: 'Namespace' object has no attribute 'version'

This makes the error more explicit.
