Fixed: The MR code decompression bug was fixed, so the feature is now available!
Fixed: The "Select all" and "Unselect all" buttons will check/uncheck all packages in the selected filter view (in clear: if you filter your packages list with "Games", using "Unselect all" will unselect every "Games" packages, instead of unchecking ALL packages).
Added: The Packages List scanner is now multi-threaded, so the ".\packages" directory scanning is much faster and don't hang the main window.
