-Added optional Exit button at the bottom-right of the main window: one user had a case where AngelLoader was displaying in "fullscreen" so the normal Windows close button was inaccesible. The new Exit button is hidden by default; it can be enabled in Settings -> Other -> Show or hide interface elements. Also added Exit item to the main menu.
-Fixed: Whitespace around header lines in language ini files (ie. "[MainMenu]") was not being handled properly, resulting in the section being incorrectly skipped if there was whitespace around said header.
-Fixed: When scanning for authors but not titles (eg. when clicking the "Rescan for author" button), in rare cases the author would not be detected and would end up blank.
