Fixed #250

If you do use xdg-open; there's no need to keep the Nautilus/Doplhin options. As every Linux DE out there follows free-desktop standards and so by using xdg-open it will open the default file manager no matter which DE you're using

Why did you remove the fallbacks? Those are still very relevant.

Edit: just read @bil-elmoussaoui 's response. I don't agree with this, this is Linux. We should not make assumptions,

@Naatan
Can you please give me an example where xdg-open doesn't work? xdg-open just uses xdg-query to get the default application for the mime type inode/directory. Which is work on every Linux system out there?
Edit:

• i might use gnome with Nemo instead of Nautilus or whatever stuff i want...

xdg-open would be called first so as long as you have it on your $PATH, Komodo would call it and if it does not exist, call something else. (e.g. Nautilus).

@Naatan those 2 file managers does not cover most popular DE's. I think it's better to add a list of some popular file managers and search for them on the PATH rather than doing if-else for DE's. What do you think? :)

UPD: oops, that was in the initial fix. I'll add more managers and revert my latest change tomorrow so we'd have some fallbacks.

It's not about it not working, it's about it being available. There is no reason to not have a fallback, it costs us nothing.
