[PATCH v2] git-remote-mediawiki: better error message when HTTP(S) access fails

My use-case is an invalid SSL certificate. Pulling from the wiki with a recent version of libwww-perl fails, and git-remote-mediawiki gave no clue about the reason. Give the mediawiki API detailed error message, and since it is not so informative, hint the user about an invalid SSL certificate on https:// urls.
