  Update LDAP.php

Update LDAP.php

Fixed to follow PSR-2 coding guidelines, proper indentation and a minor fix in equality operand (== vs ===)

Update Negotiate.php

This commit addresses Issue 268 and makes the negotiate module a bit more configurable, like the ldap-module it's leaning on..

to a default value and then executing a test to change it.

Added some very basic tests for the AttributeAlter module.

Fixed a bug in how %replace is handled when 'target' is specified to avoid multiple attribute values

Removed new call before makeException.

The `makeException` function returns an instantiated object, so the
caller shouldn't also call `new`.

  MINOR: When using HTTP protocol the $_SERVER['HTTPS'] is not set.

Checking for $_SERVER['HTTPS'] to be set, as it wasn't set when accessing simplesamlphp using HTTP protocol. This just gives a notice type error.

Update jQuery version to the latest 1.8.x. Make those templates specifying a version to stop doing it. This resolves #24, at least for some time.

Fix new attributemaps

SimpleSAML\Utils\Attributes::getExpectedAttribute(): Check if the attribute has any values, and raise an exception if not.

Refactor SimpleSAML\Utils\Arrays::normalizeAttributesArray() to SimpleSAML\Utils\Attributes::normalizeAttributesArray().

Duplicate the $state['SimpleSAML_Auth_Default.*'] entries to $state['SimpleSAML_Auth_Source.*'] where needed, while we are transitioning to 2.0. Leave those that will be removed in SimpleSAML_Auth_Default. Move the rest of the code to the new entries in the state array.
