[PATCH 13/13] Add a validation script

[Ramkumar Ramachandra <artagnon@gmail.com>]

Add a validation script along with a .gitignore. Using an existing
dump known to be correct (possibly generated using `svnsync` and
`svnadmin dump --deltas`), it compares the outputs produced by
`svnadmin load` when fed with this dump and the dump from the program.
