git-svn: nearing 1.0.0

      
This should hopefully be the last set of bugfixes I have for git-svn.  I'm
pretty satisfied with it, as I haven't needed to directly invoke svn and wait
for it in any of my day-to-day operations for doing work on svn repositories.

Most of the major changes are in 'commit' functionality where several corner-case bugs have been found and fixed.

      git-svn: fix a typo in defining the --no-stop-on-copy option
      git-svn: allow --find-copies-harder and -l<num> to be passed on commit
      git-svn: Allow for more argument types for commit (from..to)
      git-svn: remove any need for the XML::Simple dependency
      git-svn: change ; to && in addremove()
      contrib/git-svn.txt: add a note about renamed/copied directory support
      git-svn: fix several corner-case and rare bugs with 'commit'
      contrib/git-svn: add Makefile, test, and associated ignores
      git-svn: 0.9.1: add --version and copyright/license (GPL v2+) information
