Network: rethrow IOException as NOnionException (Not Tested)

[parhamsaremi]

IOExcepion caused problems in geewallet as mentioned in [1]. This commit will fix this problem by catching the IOException and rethrowing it as NOnionException.

I couldn't test this.

[1] #45

I think this whole wrapping thing needs to be done in a more DRY way.
We can't just keep adding catch clauses every place we see an exception because it's getting out of hand.
I suggest we create a WrapGuardExceptions function and use that in every place TorGuard calls to the outside world.
OR something like RunWithExceptionHandling, something like that.

Fixed in #49.
