Overriding ALL

[philipandersson]

I have a use case where I want to set a default changefreq for all routes except one. Hence why I think it would be neat to allow overriding of the ALL route keyword. Like this:

route: {
  '/': {
    lastmod,
    changefreq: 'always',
    priority: 1.0,
  },
  'ALL': {
    lastmod,
    changefreq: 'always',
    priority: 0.8,
  }
}

Changing the following line allows us to override ALL: https://github.com/hex7c0/express-sitemap/blob/90e41ba0755ccfd7f9fcd93ede7eae9a089f99d1/index.js#L318

var rr = route[uri] || route.ALL || false;

It is worthwhile to mention that I have not investigated the txt function.
