Currently, if we try to load a class from a module, and the config.php
is absent, we will get an error about the missing configuration file.

There is no reason for the configuration file to be mandatory here,
since we have reasonable fallbacks, so fix the code to make it
optional.

This should make it easier to write tests for code in modules.

Move SimpleSAML_Utilities:::getBaseURL() to SimpleSAML\Utils\HTTP::getBaseURL() and deprecate the former.

Move SimpleSAML_Utilities::addURLparameter() to SimpleSAML\Utils\HTTP::addURLParameters() and deprecate the former.

SimpleSAML_Module: add module.enable configuration option for enabling/disabling modules (issue #475).

Replace uses of utilities::selfURLhost() followed by config->getBaseURL with a call to utilities::getBaseURL().
