compiler resource loading

[Maciej Szefler <mb...@intalio.com>]

I've just checked in some changes to Guillaume's recent fix to the XSD
loading mechanism. BpelCompiler now creates URN's to identify the
resources rather than relying on real file URLs (all loading is done
by the finder mechanism). If you run into any problems with XSD/WSDL
loading let me know. One sideffect is that the compiler error messages
will be much shorter since the filenames are be relative to the BPEL
file. Also, absolute schemaLocations will no longer work (e.g.
schemaLocation="file://home/bar/baz/..." won't work).
