Dart version CLI option

It is difficult to identify which version of Dart is installed. Normally, programming languages include a -v, -version, and/or --version CLI option.

$ dart -version
Unable to find '-version'
=$ dart -v
Unable to find '-v'
$ dart --version
dart [<vm-flags>] <dart-script-file> [<dart-options>]

Version numbers are important for resolving bugs and API compatibility issues. Could we add a version flag?

Carl, can you please work with Siva to find a solution that works both for users of the standard tool chain (SVN) and at least does not break for git users?

Grabbing as this involves coordinating with build system, buildbots and release process. I had quite a few conversations with Rico on this topic already. Carl, if I need a help with a git repo in this context I'll ping you.

Check for .git directory and "git svn info" will give you the same revision information you would otherwise get from svn itself.

$ git svn info
