[fleimgruber]

Use the cask library for project management. Use ert for tests.
Adds an exemplary test for the PEP8Bear. CI is also part of project
management.

Closes #11

Note: The combination of .coafile and the :command in flycheck-coala.el works only for the provided simple test in coala-test.el. I do have a fix for this interaction, but would like to open a separate PR for it. I shot this PR first just so that we have a CI baseline established for further changes - Travis results here. WDYT?

yep we can do it incremental, I guess this is better than nothing anyway right?

I don't understand the tests but if you say they work proper they're most likey an improvement to before ;) So other than those pointed out things I think this is ready to go, I'll enable travis for this repo now.
