CocoGo for Linux Done

Today I finished the work for CocoGo 0.5.0 on Linux, which is ready for download. Basically it have same features as Windows version except:

• I use internal DND api on Windows to implement copy BITMAP of game board, therefore this feature is removed on Linux.
  
• Eclipse SWT on Linux GTK starts to support print from 3.3M1, so print feature is not available on Linux.
  

I found another limitation as I tested on Linux (my ubuntu edgy): the default file encoding is UTF-8, and the application will open SGF files with default encoding, so texts extracted from my many SGF files get messy. On my Windows in simplified Chinese version, the default is GB18030, so everything is fine. The better way is given an option to specify file encoding.

I plan to resolve these problems in version 0.5.1.
