Kchmviewer version 5.0 is released

Version 5.0 of Kchmviewer has been released.  Application went through major internal GUI redesign. Navigation tab is now a dock window, which can be moved or left floating. Now requires Qt 4.5 or higher. Fixed settings storage, but unfortunately previous application settings cannot be restored (those saved for CHM files, including bookmarks, should be fine). Fixed index parser. Default toolbars now use large icons and text labels, and is configurable through settings. Now the application can start without opening a CHM file, and startup mode is selected in settings. Added configurable check if a new version is available (once a week, can be disabled in settings). Also added OpenSuSE 11.2 RPM.
