Refactoring with new utility method, add new unittests
- New tests for StdHepCut & StdHepSplit in Workflow/Modules, TransformationPlugin, OverlayDB, ReleaseHelper
- New utility method shortens assertions on mock calls - should only be used for >1 calls
- Various cleanups (whitespace, removed unused imports, ...)
- Replace
sys.module
mocking with apatch.dict
mock (advantage of limited scope, doesn't rely on py.test internals) - Slight performance improvements (e.g. mock out logWorkingDirectory call that calls ls -laR)
- Fix SETests to use correct Xroot protocol
