Extending the other class served no purpose, so a class alias should be enough. Also, enhance a bit the exception message, and log a warning with our own logger.

This was properly solved using an autoloader-mapping

We have externalized the negotiate-module

The code generated: `$metadata['idp'] => array();` causing an error when I used this to copy the metadata and pasted it in the `metadata/saml20-idp-remote.php` file of another server.

This reverts commit 00716eb4.

This allows us to still validate XML documents (disabling the entity loader makes it impossible, as we have multiple schemas in different files), while protecting against schemas trying to import from URLs.

This reverts commit 961f5250.

This is done already when creating the document, but here we should protect as well against rogue schema files.

Apparently, links to modules must have a "./" prefix.
