Item7732: configure should check for all dependencies of the distribution - and not just the core

In TWiki:Support.SID-02171, the user failed to locate the Perl module HTML::Entities in her distribution (Ubuntu in this case). The reason is that this module is part of the CPAN distribution HTML::Parser, so there's no separate package for HTML::Entities in any Linux distribution. Installing the module directly from CPAN works because the scripts (cpan, cpanm) silently install the whole HTML::Parser distribution if HTML::Entities is requested.

TWiki's configure script already checks for a bunch of modules which are only required for some features (e.g. Net::SMTP for sending mails). In the same fashion, all modules which are required by extensions we ship together with TWiki should be checked.

TWiki:TWiki.TWikiInstallationGuide correctly lists the dependencies for WYSIWYG, but could be improved by noting that HTML::Entities comes with HTML::Parser.
