References to AS7 API jars in xts-build.xml are out of date

References to AS7 API jars which are required for building the XTS demo application and which are stated in XTS/demo/xts-build.xml are out of date. Moreover, they include full jar names, i.e. with particular versions which differ from time to time and significantly from AS7 to EAP6. This causes compile errors when building against EAP6.
