Create .travis.yml file for continuous integration.
Fix the test_max_blobs_some_of_one_tag.
Assert that the number of reported blobs is not more than max_blobs.

This will cause the test_max_blobs_zero to pass.
Do not expect the rules read from a directory to be sorted.

There is simply no guarantee for that.
Expect process_[map,results] options by default.

Assuming these options have been added after the test has been written.
