Issue/#159 - consistent names for loggers

[shukon]

Changed logger-names and removed most trailing white-spaces while at it.

Coverage decreased because a line duplicate is removed in runhistory2epm... not sure what to do about it.

[coveralls]

Coverage decreased (-0.009%) to 81.711% when pulling 9cf84fd on issue/#159 into b99dd8f on development.

I would prefer a more generic and fail-safe solution; e.g., by using CLASS.__module__+"."+CLASS.__name__

[mfeurer]

You don't need to worry about minimal coverage reduction. And I agree with Marius' suggestion for class naming.

[shukon]

I can do that, but logger-names will not be as nice for the eyes, e.g. smac.scenario.scenario.Scenario or test_scenario.test_scenario.ScenarioTest. Is that good or should I crop the last part of the module-name?

Coverage increased (+0.03%) to 81.747% when pulling 7a94c87 on issue/#159 into b99dd8f on development.
