Adds SDSC test for JClouds 1.7.1
Adds gitignore
Includes several different attempts to perform content PUTs, using two different clients. Breaks things out so it's more clear what tests are occurring.
Adds test for JClouds 1.5.5, mostly used to illustrate that code works here. On the JClouds 1.7.1 test, removes the PUT string method, as this fails on 1.5.5 as well.
Fixes spaces and such to limit the diffs between the test classes
