Reduce duration unit testing implementing their parallelization

Starting from two pull requests by @tanx and @Mithgol this commit implement the following:
- add testing of node version 4.2 LTS;
- move testing to the new TravisCI environment that is expected to be more fast;
- parallelize tests making possible to end first and to test more lasting less;
- make possible for browsertests to fail without impacting on the overall result.
