Merging latest improvements including a revamped Repo interface before more changes are to be done on the way diffing is handled

Merge branch 'improvements'

* improvements:
  Improved archive function by allowing it to directly write to an output stream - previously it would cache everything to memory and try to provide zipping functionality itself
  repo: made init and clone methods less specific, previously they wanted to do it 'barely' only. New method names closely follow the default git command names
  repo.commit_delta_base: removed
  Object can now create objects of the proper type in case one attempts to create an object directly - this feature is used in several places now, allowing for additional type-checking
  repo: removed commits_between but added a note about how this can be achieved using the iter_commits method; reorganized methods within the type as a start for more interface changes
  Added Commit.iter_parents to iterate all parents
  repo: removed a few methods because of redundancy or because it will be obsolete once the interface overhaul is finished. This commit is just intermediate
  All times are not stored as time_struct, but as simple int to consume less memory
