Added version number to binaries

Sometimes, we don't have the sources, and we want to check the version
number of the binaries themselves. (For instance when distributing
Monocypher as a library.)

To that end, I've added the global string constant "monocypher_version".
It can be used from the calling program, or scanned directly by tools.
