Only messages and documentation changes 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.
A translations update needs to follow this.
