Adds a `-version` or `--version` option to print just the version of the program for bitcoind, bitcoin-cli and bitcoin-qt. Also make it that `-help` can be used to display the help (as well as existing `--help`). Up to now, `-help` was the only option that didn't work with either one or two dashes.
