configtest.pl needs to be updated

[rjl]

The configtest.pl script needs some updates to ensure that its minimum version numbers are correct, and that it tests for all of the required applications and modules for Maia 1.0.1 and SpamAssassin 3.1.1. In particular, the script does not check the Perl version itself, and there are serious issues with Perl 5.8.0-5.8.2 (e.g. insecure dependency errors). The new Net::Server 0.93 requirement is also important to add, as is MIME::Parser 5.420 (since 5.419 breaks quoted-printable encoding).

[rjl]

Fixed in Changeset 971. The configtest.pl script has been completely redesigned along cleaner lines to make it easier to update in the future, and now tests for some of the optional modules required by various SpamAssassin plugins, such as SPF, DomainKeys?, and RelayCountry?.
