Added more example files of OpenIOC to STIX conversion.

As part of an overall effort to get more examples of STIX formatted files, I would like to have all of the OpenIOC files available in STIX format.  I think there is interest in consolidating STIX example files at a higher level, but for now, I would like to provide them in the Tools project.

If you think pulling in this many files is going to make it confusing, it's fine to leave it as is, but I figured I would give the option since I went through and already converted all the files for my personal use.
