Worth adding a regression test?

Would make sense.

To be clear, this solves the following issue:

Normal reject message

2015-12-07 20:16:52 peer=1096 Reject tx code 64: non-final: hash 54fae12b1dc553ec56137138ad28304569c9b3a69791fca5a02664b379a7d6ba

Reject message from 0.11.99+

2015-12-04 16:07:00 peer=322 Reject tx code 66: : hash 6e6f69746361736e617274206565726620646574696d696c20657461721d0000

Reason seems empty, and part of the reason message ends up in the "hash". This is due to the reject code being sent as multiple bytes instead of one, misaligning the message.

Edit: trying to think of a test. Hopefully it could fit somewhere in the Python P2P test framework, without creating a new script.

Added basic tests for rejection of blocks and transactions.
(tested that they pass with this patch, and fail without)

post-merge ACK. The extension to the test framework seems like a good idea!
