Michal Čihař - No new dictionaries tarballs on no change

No new dictionaries tarballs on no change

I've just changed scripts used to generate dictionaries for StarDict to avoid creating new tarballs when there is no real change in the data. This should avoid needless updates of the tarballs and automatically built packages when there is no real change in the data underneath.

If you somehow relied on fact that there is new tarball/package every day (or month for "stable" versions), this is no longer true and new ones will be generated only on changes.

I only hope I've tested everything properly and tarballs will really be generated on change :-).
