Small Improvements

Cygnus

0.4 release... This includes following:
• Renamed the project as Cygnus and created an icon.
• WebBrowser width is now fixed and won't change while resizing the
form.
• Changed search algorithm to not store APT data in memory. Harddisk is
fast enough. This has increased performance a lot.
• Downloaded debian packages will be stored in a seperate folder.
• Cygnus can now download depedencies.
• WebBrowser will navigate when you click on a link like "Screenshots"
etc.
• It's a lot easier to add TheBigBoss to your Sources thanks to the
hardcoded list of known sources.
• Cygnus manages Saurik's repo correctly.
