Merge branch 'hierarchyfix' into improvements

* hierarchyfix:
  Added remaining tests for new base classes and removed some methods whose existance was doubtful or unsafe
  Fixed remaining tests to deal with the changes
  commit: fixed failing commit tests as the mocked git command would always return the same thing which does not work anymore - re-implemented it in a more dynamic manner, but in the end tests will have to be revised anyway
  mode-only change for test system - this should be in a separate repository in fact so that changes are a little more self-contained and not depending on the actual source repository
  fixed issue in Ref.name implementation which would not handle components properly
  lazymixin system now supports per-attribute baking, it is up to the class whether it bakes more. This also leads to more efficient use of memory as values are only cached and set when required - the baking system does not require an own tracking variable anymore, and values are only to be cached once - then python will natively find the cache without involving any additional overhead. This works by using __getattr__ instead of __get_attribute__ which would always be called
  put Tree and Blob onto a new base class suitable to deal with IndexObjects
  blob tests fixed to deal with changes to the Blob type
  converted all spaces to tabs ( 4 spaces = 1 tab ) just to allow me and my editor to work with the files properly. Can convert it back for releaes
  Re-designed the tag testing - it does not use fixtures anymore but dyamically checks the existance of tags within the repository - it basically tests the interface and checks that expected return types are actually returned
  Intermediate commit: commit,tree and blob objects now derive from object - test is in place which still fails on purpose. Need to integrate tags which can be objects or just a special form of a ref
  Renamed lazy.py to base.py to have a file for base classes - lazy not yet changed to allow proper rename tracking
