Replace jarchivlib with commons compress

Fixes issue #7 and passes tests.  Looking for others to test / verify, if anyone is willing.  This changeset does NOT includes the errors that existed in my earlier pull request (mentioned here: https://github.com/eirslett/frontend-maven-plugin/issues/9#issuecomment-28451612 ).  Will add a comment with the result of of the Travis CI build.
