Add support for a Payment Protocol to Bitcoin-Qt.
Payment messages are protocol-buffer encoded and communicated over
http(s), so this adds a dependency on the Google protocol buffer
library, and requires Qt with OpenSSL support.
- adds 6 methods in BitcoinGUI to access some actions needed by the new
WalletView class
- updates WalletView class to use these instead of trying to duplicate
these
- cleanup walletview.{cpp/h} and remove all unneeded stuff
- this fixes problems with tabs toolbar (#2451) and export broken (#2436)
- more details in #2447
- the send coins context menu entry was not working anymore, because
a non current version of #2220 was merged onto current master
- also removes some unneeded spaces and adds a comment to
WalletModel::getNumTransactions()
