Mashes up MooseX::Getopt and App::Cmd

This module marries App::Cmd with MooseX::Getopt.

Use it like the App::Cmd manpage advises (especially see the
App::Cmd::Tutorial manpage), swapping App::Cmd::Command for
MooseX::App::Cmd::Command.

Then you can write your commands as Moose classes, with the
MooseX::Getopt defining the options for you instead of 'opt_spec'
returning a Getopt::Long::Descriptive spec.
