This is related to #478.

Don't start a <dl> when there's no content for it. Would result in "<dl></dl>".

One error left in: data-clipboard-target="#metadata"
JavaScript should probably be changed to check for id instead of a proprietary attribute.

Add mandatory cols-attribute for non-CSS compatible browsers.

We're one column short

The segfault happens in the coverage report. Since we send coverage
info only with PHP 5.6, avoid running it entirely, saves buildtime aswell.

- Attributes which can be get from LinkedIn are now configurable

Update to phpunit 4.8. Last version with php 5.3 support

Update test notes to point to the 4.8 documentation and describe
how to run an old version of phpunit from composer's bin dir.

`noop()` is a method on the template after all.

This makes instanciating the Translate/Template-class unnecessary.

For #455. Note that if translation tags were domain-free strings, the
mapping from tab to tabtitle would be redundant. It would still be
necessary to mark the strings as noop however.

For #454, #455

For #455

Deprecate the certFingerprint option.

There was a typo in the name of the class, where the module was referenced as "smartattribute" instead of "smartattributes".

This is needed for the autoloader to work, or code calling class_implements(), among others.

Added checks for Date/Time, JSON, cURL and Session.

Even though the default "exact" is used by most people, and few products support anything else, there's people asking for this.

Since we have updated the version of the SAML2 library in use, we should use SAML2\Constants now.

Instead of keeping SAML-specific error exceptions in lib/SimpleSAML/Error, it makes more sense to have those in the saml module. Now that we have the recent NoAvailableIDP and NoSupportedIDP errors moved there, it's time to change the code implemented recently that uses them.

This makes it easier to identify error conditions and return errors to an SP. More known errors should also be added here.

The SAML2 IdP should keep the RequestedAuthnContext in the state array, so that authentication sources (or processing filters) can use that information during authentication.

Removed html extension in Twig files

This is due to the update of the SAML2 library, that caused several other bugs, mainly with attributes like eduPersonTargetedID, which should always be an SAML NameID.

It is possible that the current script ($_SERVER['SCRIPT_FILENAME']) is inside SimpleSAMLphp's 'www' directory. However, even if that's the case, we should not enforce our base URL (as set in the 'baseurlpath' configuration option) if the request URI ($_SERVER['REQUEST_URI']) does not contain the relative path to the script. This is the case of AuthMemCookie, for example, where accessing a random URL protected by Apache, leads to the execution of a SimpleSAMLphp script, where SimpleSAML\Utils\HTTP::getSelfURL() must not try to be smart when guessing the current URL.
