Short verbose flag '-v' doesn't work

[zabawaba99]

If you specify the global option -v on any command it prints the version

$ exercism -v debug
exercism version 2.2.0
$ exercism -v submit
exercism version 2.2.0

I dug around a little it and it looks like codegansta/cli checks for a few flags (-v) included when it runs the app. I don't see any way to support the -v at the moment without changes to codegansta/cli.

I'd be more than happy to make a PR to remove -v from the verbose option.

It seems like the long flag name doesn't work either

$ exercism --verbose debug
exercism version 2.2.0

Good catch, it seems that the references to the debug flag, now verbose, were not updated. We should update all the references to use the new "verbose" flag.

There is actually an open issue for it on codegansta/cli urfave/cli#254
