-=head2 unhashdir

-This function unhashes the hash of hashes generated by hashdir().
-This directory unhashing routine is the personal work of Chris Nighswonger (fbcit).
-Modified here to build koha makefile. It lists all files and where to install each one.
-It then returns a hash reference suitable for the PM variable above.
