External URLs in sitemap

[lazybadger]

Folllow-up for #47

Some subset of external links from site, referenced in main page content, may appear in sitemap (with default setting of plugin). Only one possible correlation is reliably discovered in addition to old (still open) issue from Jul 2017:

• Sites on clean Grav core doesn't have external URLs in sitemap, while site with Gantry-based theme got some external URLs in sitemap

Full list of my externals and status of inclusion:

I can confirm this issue happens with a Gantry based theme.

I've removed the external URLs by default in the upcoming version 2.0 of sitemap. These are set with external_url: http://something.com in the frontmatter.
