Title: Add application description to the help msg

It was there already (?), I just put it in the help msg.

```javascript
program
.version('0.0.1')
.description('simple application description')
.option('-f, --foo', 'enable some foo')
.option('-b, --bar', 'enable some bar')
.option('-B, --baz', 'enable some baz')
.parse(process.argv);
```

will show:
```
Description: simple application description

Usage: app [options]

Options:

-h, --help output usage information
-V, --version output the version number
-f, --foo enable some foo
-b, --bar enable some bar
-B, --baz enable some baz
```
