Earlier, 'git prune' would prune all loose unreachable objects. This could be quite dangerous, as the objects could be used in an ongoing operation. This patch adds a mode to expire only loose, unreachable objects which are older than a certain time. For example, by git prune --expire 14.days you can prune only those objects which are loose, unreachable and older than 14 days (and thus probably outdated). The implementation uses st.st_mtime rather than st.st_ctime, because it can be tested better, using 'touch -d <time>' (and omitting the test when the platform does not support that command line switch).
