JuffEd 0.6.0 release

It is out!

Main changes:

• splittable document view
  
• using icons installed in system (on Linux/BSD)
  
• changing line endings (auto-detection and manual changing)
  
• auto-detection of syntax highlighting based on document's first line (for some file types)
  
• displaying of invisible symbols (tabs, spaces, line wraps)
  
• context menu for status bar (syntax, charset, line endings)
  
• improved and more powerful plugin API
  
• CMake syntax highlighting
  
• Chinese (Simplified) localization
  
• new application icon
  
• added icons of sizes 16 and 24 to the default icon theme (got rid of blured icons)
  
• many small UI improvements
  

Also it's decided to take a new version numeration style: now odd numbers (0.5, 0.7, ...) mean development versions, even numbers (0.6, 0.8, ...) mean stable releases.
