A lot of changes to support the new UWOBO stylesheet processor:

Modified Files:

Makefile.in : of course, some new source files
configuration.ml.in : better support for configuration variables and overriding
getter.ml : now it is just a wrapper for clientHTTP, still needs some serious
	rearrangement
getter.mli : the interface changed a little bit
mmlinterface.ml : call for the initialization of the processor
pxpUriResolver.ml : the resolver is now more reliable
styleConfiguration.ml : retrieve and parse stylesheet configuration
xsltProcessor.ml : it is now a simple wrapper for xsltProcessorHTTP

Added Files:
clientHTTP.ml : a simple client HTTP (a minimal wrapper for netclient)
xsltProcessorHTTP.ml : send HTTP requests to the processor
xsltProcessorUDP.ml : just in case we want to implement both
	methods for invoking the processor
