Added another set of test cases and fixed issues with server/client code

[rashmihunt]

1. Fixed Client.js - removed logic to wrap operationName for DocLitWrapped case since the code already does it in another point of execution.
2. Fixed server.js - while calculating outputName, code assumed that there is a 'part' with the name "body" which is incorrect.
3. Added RPC/Literal test with complex type params
4. Added RPC/Literal test with simple type params
5. Added RPC/encoded test (skipped for now)
6. Added Document/Literal test
7. Added Document/Lietral-wrapped test
8. Added detail comments for each of the test case above with the actual input/output env
