svnwrap: use get_file instead of list_props during replay This patch has an enormous effect on the time taken to import commits which add many files. Specifically, it makes them much faster for pulls over the network because it avoids creating a new connection to subversion for every added file. In my testing, it dropped the time taken to import a revision that adds ~6500 files from approximately 1 hour to 30 seconds. I believe this test is representative of real-world performance improvements.
