[golist] Issue #21: Overhaul CLI

[Elliott Sales de Andrade]

qulogic reported a new issue against the project: `golist` that you are following:
``
I don't really like the way the command-line arguments are specified right now.
Everything is an optional flag which requires writing out a redundant argument name. This
would be even worse with #4. Also, urfave/cli doesn't seem to follow POSIX semantics,
which is a bit annoying.

I'd rather the CLI look something like: `golist <command> <package-path>
[<package path> ...]` where `<command>` is one of the original flags that
specified output modes. All the other flags could remain optional.

This could maybe be done with `pflag` instead for optional things and just switching
commands ourselves. Or maybe using `cobra`. Probably depends on how heavy these things
are.

@eclipseo Please play a little with `modist` and tell us if it is better. I tried to fix
the CLI interface.

`cobra` is difficult to use in a core utility like `golist`. It has lots of requirements,
so bootsrapping a Go stack that required cobra to work would be quite difficult.

True, `cobra` uses quite a bit; `pflag` has no dependencies though, which would be even
better than `urfave/cli`.
