Ghostscript 9.01 final

[Till Kamppeter <till.kamppeter@gmail.com>]

Hi,

I am packaging GS 9.01 final now (official release tomorrow). Simply 
updating the source code of the Ubuntu package to the 9.01 final release 
works without problems. I also succeeded to use the external libijs 
(removing the ijs/ directory in the repackaging and build-depending on 
libijs-dev.

Now I will look into merging in all changes of your current Debian package.

Jonas, I recommend that you wait with updating the Debian package to 
9.01 final until I have finished. When I am ready, simply merge back 
from Ubuntu.
