More style additions and corrections for the test suite

I've made a correction to the wrpc:signature tests I previously 
contributed. I defined the namespace incorrectly as 
http://www.w3.org/2006/01/wsdl/style/rpc 
instead of
http://www.w3.org/2006/01/wsdl/rpc 
This may be a place WSDL 2.0 authors make mistakes due to the similarity 
of the two URIs and the fact that they're both related to RPC.

I have also created tests for the IRI and Multipart styles.

I've attached two patches.

test-suite-styletests.patch - contains my additions and updates
test-suite-styletests-withreports.patch - contains my additions and 
updates and the updated reports from running the build included in the 
test suite (the reports on the website look out of date)

Thanks,
