Only messages for now, executable names and other file names can be changed later if necessary and safe. Do not do an all-sweeping change. Some occurences of Bitcoin-Qt need to be kept: - Applicationname: this is used to determine the registry entry names, we don't want to lose settings over a silly name change. - Where it refers to the executable name instead of the product name.
