Added restoreWalletMode global variable. OperationModel and walletOperation removed. The restoreMode argument has been added to the createWalletSignal signal. The newWalletButton and restoreWalletButton buttons set a different argument value in the createWalletSignal signal. The DapCreateWallet.qml and DapRecoveryWalletRightPanel.qml panels use the value of the restoreWalletMode variable.
