Provide support for inXSD etc in ESB Config Editor

Adding support for these in the Tree view would help eliminate the need for the user to hand edit the jboss-esb.xml file in the source view. Example is

<actions faultXsd="/policyQuoteFault.xsd" inXsd="/policyQuoteRequest.xsd"
outXsd="/policyQuoteResponse.xsd" mep="RequestResponse">
