improved application for Windows: added tray icon (near clock); left click on icon pauses/resumes download; right lick opens menu with important functions; console window can be shown/hidden via preferences (is hidden by default); new preference to automatically start the program after login; new preference to show browser on start; new preference to hide tray icon; menu commands to show important folders in windows explorer (destination, etc.); on first start the config file is now placed into subdirectory "NZBGet" inside standard AppData-directory; default destination and other directories are now placed in the AppData\NZBGet-directory instead of programs directory; this allows to install the program into "program files"-directory since the program does not write into the programs directory anymore; the program exe has an icon now; if the exe is started from windows explorer the program starts in application mode; if the exe is called from command prompt the program works in console mode
