Fixed a bug where the editor would exit because of a boost exception when browsing to a directory that the user does not have access to. The vfs now catches the boost exception and throws a FIFE exception. Updated the filebrowser to catch the exception and display a warning to the user. fixes[t:413]

audiotest1.ogg & left_right_test.ogg are based on the song "Maybe" that shipped with the game Fallout 1. These files have been released by Interplay later under a license that permits you to copy and spread these files but without making profit of it!
