- Custom datadir/server argument logic moved into configuration, out of main.
- Updated the validator config directory structure, as per issue #253 suggestions
- Removed the 'generate 3 random keys' function
- Updated the README to reflect new structure
- Just exit if there are no keys, don't generate any (this is for accounts_manager, in a separate commit).
- Created a lib.rs file, so that the validator client configuration can be included by external crates.
