This PR is potential fix for issues #507, #575 and #1054. It addresses JS errors related to the use of unescaped string literals inside keywords, and it is based in a previous PR (#509) by user @jrfnl. It's been successfully tested by the OP of #507, @blafrance.

Fix issue #1073 date localization

Fixes dates not always being localized in the `wpseo_replace_vars()` function.

Also:
* similar date localization in metabox preview snippet (after all Google is localized too)
* minor efficiency tweak in `wpseo_replace_vars()`
* ensure that dates in sitemap are *not* localized - this might fix some invalid date format issues people are having when validation the sitemap in GWT
Fix issue #1080 - empty post id notice
Fix issue #1068 - error in sitemap_index.xml if post type does not contain any posts

Also fixes a typo in the same line - this may well be the cause of the incorrect sitemap last modified dates as reported in #930, #883, #1066, #525, #873
Fix issue #1045 - 'breadcrumb_last' class was missing on homepage
Use the correct HTTP protocol for responses, props @Fab1en and @jrfnl for the method, updated for readability and so extensions can use it too. Fixes #983
