Title: QR Code generation via libqrencode

Added QR Code generation button to address book page, a dialog to display the result including fields for label, message, and request amount (the latter visible only for personal addresses). Images can be saved to disk. Codes use the 'bitcoin' URI scheme described here: https://en.bitcoin.it/wiki/URI_Scheme

Enabled via qmake option 'USE_QRC'.
