Title: Added switch to disable accumulators + bugfix + api change

This includes the bugfix for @AHeise (https://github.com/stratosphere/stratosphere/issues/349), a small change in the API as proposed by @rmetzger (https://github.com/stratosphere/stratosphere/issues/119) and the introduction of a switch to disable accumulators per job.

Regarding the switch

- I found that it's better to store the disableAccumulator in the job configuration object (and not in each TaskConfig). This way we have less overhead and I can easily read the property in the JobClient to avoid the additional RPC call if accumulators are disabled.
- Let me know if you propose other cli-options. I could not test it, because I always get the following error

bin/stratosphere
