Naufrago! 0.3 release

Hi there folks,

Finally I decided to release the 0.3 version. I did publish the roadmap here a while ago (you can find it here: https://sourceforge.net/news/?group_id=333054&id=294229\), and apart I added a couple of things.

This is the addendum list:

- The number of unread entries on 'Unread' special folder has been fixed.
- Now the launching script logs errors in order to try to identify app issues.
- Automatic online version checker feature (manual launch is also possible).
- Important rework in the way feeds are stored to avoid repeated entries (happens with some feeds with bad date field or bad date parsing).
- Locale english fallback when no supported locale is found.
- Documentation update.

Well, and that's all. You can read more on this on my blog (http://enchufado.com/). Although it's spanish, Google Trans normally does a good job.

Have a happy new year reading RSS! ;)
