Update more URLs to use https
Mostly plain http -> https replace, if https works.  If there is a HTTP
redirection, use the redirect target (unless it's a mirror or l10n like
"https://kde.org/zh-cn/").

Some non-trivial change:

* www.mnogosearch.org is dead.  Not sure how to replace, so deleted.
* use https://github.com/cacalib/libcaca for libcaca.
  http://caca.zoy.org/wiki/libcaca seems out-of-date.
* http://www.speech.cs.cmu.edu/flite/ is dead, replaced with github repo
  link.
