changed some comments
[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
Remove unused imports in macdeploy script
add DEFAULT_UPNP constant in net

- as this is a shared Core/GUI setting, this makes it easier to keep them
  in sync (also no new includes are needed)
doc: Clarify wording about testing in README.md

Weaken and clarify the wording a bit, it currently implies that we get
more pull requests than we can ever handle which discourages
contribution.

osx: Fix missing dock menu with qt5

Qt5 Removed the qt_mac_set_dock_menu function and left no replacement. It was
later re-added and deprecated for backwards-compatibility.

Qt5.2 adds the non-deprecated QMenu::setAsDockMenu(). Use that when possible.
