Resolution of missing cobertura lib files in master repo

Per comments from Olga and subsequent discussion on Hangouts (thanks Olga!!), the master branch was not running successfully after my merge earlier today.  Problem turned out to be a line I had in the root ".gitignore" that was excluding the folder containing the cobertura Jar file and its dependency's Jar files (/lib/cobertura).  I just cloned the entire FileSieve repo to a new folder on my PC, switched to this branch (which now has the correction) and verified that the "/lib/cobertura" folder and all files are now included.  Running "ant all" also succeeded.  As such, I will merge this new pull request in just a few seconds to get our master branch back to a good state.
