Improved XML validation when XSD files are saved

[angelozerr]

When a XSD file is saved, it loop for all opened document and for each XML document, it checks if the saved XSD file bind the the current XML file. To do that DOMDocument#useSchemas is called. This method must be improved

1. Windows OS problem

When XSD file is saved on Windows OS, it should revalidate all bound XML files, but it didn't do that.

After debugging, I have this error:

java.nio.file.InvalidPathException: Illegal char <:> at index 2: /C:/Users/azerr/Downloads/data_gxl_minimal++_minimal++_OHNE_DOC.gxl/book.xsd

2. Manage only xs:schemaLocation, xs:noNamespaceSchemaLocation binding

If opened XML file is bound with a XML catalog, XML file assocotaions, DOMDocumnt#useSchemas doesn't takes care of this binding kind.

To fix both 1) and 2), the DOMDocumnt#useSchemas must be rewritten by using resolverExtensionManager#resolve.
