Add TILs section, with Atom support and i18n

- add i18n logic to support translated TIL entries and listing;
- make the website title less tied to a blog: "EuAndreh::blog" ->
  <web>EuAndreh</web>;
- remove old Atom feed link aliases;
- remove feed.all.atom and it's link in the about page;
- create Atom feed for TIL entries;
- show blog and TIL Atom feed on their listing pages (index and tils-listing);

  instead;
- also lint, assert-content and assert-unique-ref of TILs;
- fix wrong "post.date" in pastebin entry in site.json;
