Slight comment and print output changes in s3 tests
Created eucaops.get_traceback() for ops-level error debug. Also handle exception during install_riak_cs for case where the lookup of RIAK component in the config fails--just skips the install.
Ignore pydev and project config files as well as eclipse settings dir
Remove the .project .pydevproject and .settings/* from git
