data files prefix

Could you make possible to put the data files in `/usr/share/nonsense` and the executable in `/usr/bin`?
If I do this split, it can't find `default.data` (even if passed on commandline `nonsense -f /usr/share/nonsense/default.data`)
`Error opening default.data... No such file or directory`

To mak it work, I have to `cd /usr/share/nonsense` first
