Report the remote server's $VERSION somehow

[thaljef]

At one time, we had a separate version command that would report the versions of Pinto, Pinto::Remote and Pinto::Server. These were shipped separately so it was quite possible for each to have a different $VERSION.

But then I decided to ship all those modules in one distribution and give them the same $VERSION. At that point, I removed the version command and just relied on the built-in --version option that App::Cmd provides.

However, neither one of those would tell you what version of the code is running on a remote server, which is very useful to know when reporting bugs or trying to diagnose one.
