Spring Warp MVC XSD configuration

Since ARQ-1317 has been completed, now we could add extra XSD that would be a shortcut for configuring the Warp within the spring:

    <warp:enable-interception />

The suggested xml namespace is:
http://jboss.org/schema/warp

Xsd file should be created with additional alias defined in spring.schemas:
warp-spring.xsd // which will be an 'alias' to most recent xsd version
warp-spring-1.0.xsd // the schema file for all 1.0.x versions
