throw error when keys not set correctly

[myou]

May need some confirmation on this, but here are the customer's words:

If the api and private key were not set (I think just my private key was
set because up to the point where I started listening for the successURL
call I had been working with the javascript libraries), a fatal error is
thrown somewhere in the Recurly libraries that I assume gets swallowed by a
try block. I am not sure where in the code, but if I don't have both keys
properly defined execution stops with no there are no errors logged in any
logfile. I am just left scatching my head about why the code stops.

I tried to reproduce this and the errors are thrown properly for me.

Uncaught exception 'Recurly_UnauthorizedError' with message 'Your API Key is not authorized to connect to Recurly.' in /home/mbeale/php/recurly/lib/recurly/response.php:50

Got a similar error when trying to sign without a private key.

@mbeale I also cannot reproduce this. So until someone else encounters the same problem, let's consider the issue closed.

Got the same error while using my sandbox account private key.
