exo-open should set a default app automatically if one is not set
When I try to open the terminal in thunar or open an .html file from thunar, I get an error that says that the default terminal emulator/web browser is not set. I think rather than returning an error, it should try to look for a web browser. I understand that this is more of a feature request than a bug report, but many other desktop environments already have this feature and it makes it very frustrating to try to use thunar on another desktop environment.
