My changes leave all tray icon and menu creation/initialization logic
untouched. It only shows or hides the icon according to the setting.
A new checkbox was added to the OptionsDialog under the Window tab. A
bool option named "hideTrayIcon" was added to OptionsModel. This
checkbox was mapped like other all options to the OptionsModel.
A signal was added to the OptionsModel for broadcasting changes the the
hideTrayIcon option. This signal was connected to a new slot added to
BitcoinGUI named setTrayIconVisible(bool). The slot simply hides or
shows the trayIcon in BitcoinGUI according to the parameter recieved.
I made a subclass of QMessageBox that disables the send button in
exec() and starts a timer that calls a slot to re-enable it after a
configurable delay.
It also has a countdown in the send/yes button while it is disabled
to hint to the user why the send button is disabled (and that it is
actually supposed to be disabled).
