Clash of the Lambdas, updated

We would like to provide a revised version for our Clash of the Lambdas paper that was accepted in ICOOOLPS'14. We would also like to thank the reviewers, the conversations on our Github repo and other readers that have sent comments via email and strengthened this paper.

In the revised version:

1. we used a fixed heap with 3GB. The GC throughput was improved and results are more balanced
2. we discussed briefly why we chose not to use targeted JVM flags
3. we discussed @specialized and miniboxing
4. we added a new benchmark that tests a streaming operation that avoids automatic boxing of our input data
5. a subtitle was added
