If a complex structure of symlinks is used in the tree it's impossible to apply a created delta patch.

Steps that will reproduce the problem:
Extract the files from http://dl.dropbox.com/u/61193827/7dje76shi8dsi78sdf/Impossible%20Delta.zip```
BinaryDelta create A B patch
BinaryDelta apply A C patch
```
What is the expected result:
C is identical to B

What happens instead:
BinaryDelta says *Destination doesn't have expected hash XXX != YYY*
