. Fix 'webcheck' target url generation in directories other than 'www/en'. In
these cases we get urls like 'http://www.FreeBSD.org///ru//java/', etc. On such urls webcheck fails immediately with 403 error code. So, cleanup multiple slashes.
. Make 'checkmissing' output more compact and readable. Avoid
printing '===>' in case if current directory does not have anything to report. Also print each missing entry on separate line to make output more readable.
