[Qt] ensure payment request network matches client network

- replaces checks in SendCoinsDialog::handlePaymentRequest() that belong
  to PaymentServer (normal URIs are special cased, as only an isValid
  check is done on BTC addresses)
- prevents the client to handle payment requests that do not match the
  clients network and shows an error instead (mainly a problem with
  drag&drop payment requests onto the client window)
- includes some small comment changes also
[Qt] Fix Transaction details shows wrong To:
Use pnode->nLastRecv as sync score directly

NodeSyncScore() should find the node which we recv data most recently, so put a negative sign to pnode->nLastRecv is indeed wrong.

Also change the return value type to int64_t.

I have now removed unnecessary html so this should make life easier for
translators and you @Diapolo :). What do you think?

The size of the window needs to change when you make links clickable.
