Reduce the peer charges for well-behaved peers:

- Fix an erroneous high fee penalty that peers could incur for sending
  older transactions.
- Update to the fees charged for imposing a load on the server.
- Prevent the relaying of internal pseudo-transactions.
  - Before: Pseudo-transactions received from a peer will fail the signature
    check, even if they were requested (using TMGetObjectByHash), because
    they have no signature. This causes the peer to be charge for an
    invalid signature.
  - After: Pseudo-transactions, are put into the global cache
    (TransactionMaster) only. If the transaction is not part of
    a TMTransactions batch, the peer is charged an unwanted data fee.
    These fees will not be a problem in the normal course of operations,
    but should dissuade peers from behaving badly by sending a bunch of
    junk.
- Improve logging: include the reason for fees charged to a peer.
