Paint.NET 3.08 Beta

This is mostly a service release that fixes some bugs, while also improving keyboard / accessibility cues for some dialogs.

* Fixed: Pasting an image from Office 2003 applications now works (e.g. Excel 2003 graphs).
* Fixed: Some dialogs were not indicating which command button was the default. These buttons now have a highlight to indicate which one will be activated if the user presses Enter or Space.
* Fixed: Some minor keyboard navigation issues with task dialogs
* Fixed: Performance issue with the File->Acquire submenu taking a long time to appear
* Fixed: Window activation issue when the Print wizard was finished / closed
* Fixed: Crash when there was 1 image open and the user pressed Ctrl+Q and then Ctrl+W
* Fixed: Minor performance issue if the user had 1 modified image open and then canceled the "Save changes?" dialog
* Fixed: Misbehaving filetype factory implementations (plugins) will no longer cause a crash
