Updated scrutinizer configuration to analyze code coverage.

Changes to scrutinizer means that this was currently not running.
Updated dependencies.

It is OK to use latest versions of Phing and PSR log within the current
major release.
Updated SOAP request/response fixtures.

Unsignificant changes for our part though.
Disable PHP WSDL cache when extracting information.

If the cache is enabled when creating the SOAP client instance we risk generating code based on obsolete information.
Conflicts:
	src/Wsdl2PhpGenerator/Xml/WsdlDocument.php
Fixed default null value for subclass parameters.

Constructors for subclasses inherit the parameters for their parent classes. If the ConstructorParamsDefaultToNull configuration option is used these should default to null as well.
Make setters chained. #133

* Add Type::phpNamespacedIdentifier
* Test namespaced setters
* Test chained setters
Remove setAccess as discussed in #134

Merge pull request #144 from garex/issue/3.x-remove-set-access

Remove setAccess
Add support for XSD includes.

We treat both includes and imports as referenced schemas so rename variables accordingly.

Implement test case
Fix identifier when loading dependencies.

Use the PHP identifier in case in case it has been modified due to
unsupported characters, uniqueness etc.
Add configuration option automaticallyConvertDateTime (--convertDateTime)
Refactored base test classses.

Split generator specific code into a  code generation class which is broadly usable and a functional test class usable for reading WSDLs and testing generated files.
Finished implementation date time handling.

- Convert SOAP datetime to the PHP DateTime class
- Removed option for enabling this. This should be the default behavior.
- Implemented unit and functional test.
Implemented initial support for method type hinting

- Only supports DateTimes (and arrays) for now
- Updated test cases accordingly
Reintroduce changes lost when rebasing.
