Merge branch 'index' into improvements

* index:
  index.add: Finished implemenation including through tests
  When parsing trees, we now store the originan type bits as well, previously we dropped it
  cmd.wait: AutoKill wrapped process will automatically raise on errors to unify error handling amongst clients using the process directly. It might be needed to add a flag allowing to easily override that
  added head kwarg to reset and commit method, allowing to automatically change the head to the given commit, which makes the methods more versatile
  refs.SymoblicRef: implemented direcft setting of the symbolic references commit, which possibly dereferences to the respective head
  index.commit: implemented initial version, but in fact some more changes are required to have a nice API. Tests are not yet fully done either
  actor: added __eq__, __ne__ and __hash__ methods including simple test
  index.remove implemented including throrough test
  Implemented index.reset method including test
  IndexEntry is now based on a 'minimal' version that is suitable to be fed into UpdateIndex. The Inode and device information is only needed to quickly compare the index against the working tree for changes, hence it should not be that dominant in the API either. More changes to come
  Added notes about git-update-ref
  Refs can now set the reference they are pointing to in a controlled fashion by writing their ref file directly
  Added TagRefernce creation and deletion including tests
  Implemented head methods: create, delete, rename, including tests
  refs: added create, delete and rename methods where appropriate. Tests are marked, implementation is needed for most of them
  Added frame for IndexFile add/remove/commit methods and respective test markers
  Added repo.index property including simple test, and additional ideas in the TODO list
  Renamed Index to IndexFile, adjusted tests, it will only operate on physical files, not on streams, as Indices are not streamed by any git command ( at least not in raw format )
