change safeURL to absLangURL in site-navbar menu for multi languages

[ghost]

After multi-language setting is enabled, once I change to another language, and click the site navbar menu, the site url may redirects to the default language menu.

The absolute URL function you use in the file layouts/partials/header.html is safeURL. Changing it to function absLangURL will solve the issue.

You can see the effect on my blog.

@MaxdSre Please, remove the last commit from this PR, because it's not related to the initial issue.

As for your proposal about sitemap. I like to have an option for this in configuration. But now it could be a braking change for some users.

[Zebradil]

Also, the first commit brakes links with non-standard schemas as it's explained in docs:

Without safeURL, only the URI schemes http:, https: and mailto: are considered safe by Go templates. If any other URI schemes (e.g., irc: and javascript:) are detected, the whole URL will be replaced with #ZgotmplZ. This is to “defang” any potential attack in the URL by rendering it useless.

[Zebradil]

But in the following way we can handle it:

{{ .URL | absLangURL | safeURL}}

@Zebradil I have remove the last commit, and I also tested {{ .URL | absLangURL | safeURL }} in my blog, it still works well on my online blog.

[Zebradil]

Good stuff. Let's wait for @xianmin.

@xianmin BTW, I'd take in consideration @MaxdSre's proposal about sitemap. It's not important for me, but argumentation was good and it can be useful.

[xianmin]

So, in the end, should we change to {{ .URL | absLangURL | safeURL}} ?
The code I checked is still {{ .URL | absLangURL }}.

[Zebradil]

Yes, we need to change it. Yesterday I saw another version. Probably, force push was done to the source branch.

@Zebradil @xianmin I push a new commit to change it to {{ .URL | absLangURL | safeURL }}.
