actions for history items can now be performed for multiple (selected) records: post-process again, download again, mark as good, mark as bad; extended RPC-API method "editqueue": for history-records of type "URL" the action "HistoryRedownload" can now be used as synonym to "HistoryReturn" (makes it easier to redownload multiple items of different types (URL and NZB) with one API call)

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

created installer for windows; the program is installed into "program files" by default; the working directory with all subdirectories is now placed into "AppData" directory; the batch files nzbget-start.bat and nzbget-recovery-mode.bat are not needed and not installed anymore
