Various fixes and improvements
* GIT_PYTHON_TRACE now behaves correctly for fetch, and pull (i.e. if as_process is used)* Improved parsing of fetch head informationHowever, there is still a messy bit that tries to bring together fetch progress informationwith fetch head information. Even though it works now, an alternative implementation shouldbe attempted.
